Suspension Clamp Supplier

Suspension Clamp Supplier

A suspension clamp holds an aerial cable or conductor on an intermediate pole. It carries the vertical load of the span and lets the cable move a little along its length as temperature and wind change, without letting it leave the groove or rub against the pole hardware. It is not a dead-end: it never has to hold the full line tension, and it should not be asked to.

We supply them for 4-core LV-ABC bundles, single insulated conductors and round fibre cable, in aluminium alloy and galvanised steel. 19 models carry a published cable range and breaking load on this page. Start from what you are suspending, not from the model name: several bodies in this range are sold under more than one name, and three share one.

Three ways the range is written

4x16-4x35mm² is a four-core bundle, 16–35 mm² per core. 25-95mm² is a single insulated conductor. Ø5-8mm is a round cable measured across the sheath, which is how the fibre clamps are sized. Order from the wrong notation and you get the right shape in the wrong size.

Not sure which model

Send the cable type, the conductor section or the cable diameter, and the breaking load your pole design calls for. Where two models share a range, we confirm which body your drawing expects before quoting, not after.

What the clamp does to the cable, and what it must not do

The cable sits in a groove under a keeper, so the load is spread over a length of sheath rather than pinched at one point. That is the whole job. A clamp that pinches will still hold the span and still damage the cable: the sheath creases, water enters, and the conductor fails inside the insulation a few seasons later, at a point that looks fine from the ground.

The clamp also has to let the cable move. Spans expand and contract with temperature, and wind makes them swing. A rigid grip transfers that movement into the pole hardware; a correctly sized suspension clamp lets the cable travel a few millimetres and return, which is why the range is given as a range and not as one exact diameter.

What it must not do is carry line tension. At a dead-end, at a corner pole or across a long river crossing, the load runs along the conductor rather than across it, and that is a tension clamp’s job.

Three things the clamp decides

Where the load goes. Spread along the groove, not pinched at one point, so the sheath is not creased where the clamp sits.

How much the cable can move. A little longitudinal travel takes thermal and wind load out of the pole hardware instead of into it.

Which load it never sees. Tension duty belongs to a tension clamp, at every dead-end and corner.

All figures are the published values on each product page. A 4x value is the section of one core in a four-core bundle. An Ø value is the cable outside diameter. Brackets are mounting hardware and carry no cable range.

Models that look alike, and how to tell them apart

Four groups in this range cannot be separated by looking at the catalogue. They share a conductor range, or a model name, and differ in the figure that decides whether the clamp survives the span.

Read the note under the model you picked above, then check it against the matching group here.

SHC, three builds under one name

The fibre clamp is listed three times as SHC. Two of them take a 5–8 mm cable, one at 4 kN and one at 8 kN; the third takes 8–12 mm at 8 kN. Ordering “SHC” on its own gets you a clamp that fits and may be rated at half the load your pole design assumed. Give the cable diameter and the load.

1.1A / 1.1C

Both cover a 15–95 mm² conductor, and the only published difference is the breaking load: 9 kN against 4 kN. The 4 kN body is the light one, for a service drop or a short span. Put it where the drawing says 9 kN and the clamp becomes the weakest point on the pole.

ES1500 / ES1500A / 1.1B / 1.1D

Four different bodies, one set of published figures: 25–95 mm² and 12 kN, all four. PS1500 and 1.1F are the same story at 15 kN. Nothing in the published data separates them, so they cannot be told apart from a catalogue: match the model code on your bill of materials, or send us the pole hardware they have to fit and we match the body to it.

PS25/120 and PSP25-120

Same bundle range, 4x25–4x120 mm². The PS25/120 is published at 10 kN, the PSP25-120 at 13 kN. On a normal distribution span either will hold; on a long span in a wind or ice area the 3 kN difference is the reason one is specified and the other is not.

Where a suspension clamp is the wrong part

Three cases come up often enough to state plainly, because in each of them a suspension clamp will fit and will look right on the pole.

A dead-end or a corner pole

The conductor is terminated there, so the load runs along the line. That is a tension clamp: see the tension clamp range. A suspension clamp used at a dead-end will hold until the first cold snap and then let the cable pull through.

A span long enough to load the clamp

Suspension clamps are published at 4–22 kN of vertical load. On a long crossing, the vertical component of a tight conductor can approach that. Send the span, the conductor and the sag and we will check the clamp against the load rather than against the cable size.

A bare conductor sized only in mm²

Our published ranges are written for insulated ABC and for round fibre cable, both of which have a known outside diameter. For bare AAAC or ACSR, the diameter for a given mm² is smaller, so the groove that suits the section may not seat the conductor. Give us the conductor diameter and we will confirm the body.

What a first order costs, and how it ships

Price, minimum quantity, lead time and payment decide whether a clamp order is worth placing. These are the bands this class of product trades in, so you can budget before you ask.

The rest of the termsWhat is fixed before the container is loaded, and what is not.

Samples

Free of charge. You pay the courier and we credit it back against the first order. Posted within two to three days of the drawing being confirmed.

Payment

Small orders are paid in full when the order is placed. On larger orders, 30% T/T as a deposit, with the balance settled before shipment. The quotation states which of the two applies to your quantity.

Port and Incoterms

FOB, CFR or CIF from Ningbo or Shanghai. Give us the destination port and we quote the freight leg separately, so you can see what it adds to the landed cost.

Packing

Packed in export cartons, palletised or loaded loose in the container. Carton marks can carry your model code instead of ours, and we send the carton list with dimensions and weights before you book the freight.

Mixed models

One shipment can carry several models. Each is packed separately so your store can issue it without repacking.

Before the container leaves

Photographs of the finished parts and the packed cartons, and the mill certificate for the steel. Third-party inspection is welcome; tell us the date and we arrange access.

Treat these as budget bands, not a quotation.

Send the model, the quantity and the destination port. We reply with a firm price, the packing list and a lead time against your date, within one working day.

Manufacturer, not a trading desk

GGLDF is Zhejiang Ganggu Electric Power Technology Co., Ltd., registered in Yueqing, Zhejiang. We manufacture for utility contractors, EPC firms and distributors, and we build these product lines rather than reselling them.

The range covers suspension clamps, tension clamps, insulation piercing connectors, parallel groove clamps, busbar accessories, cable lugs and cable terminals. Where a project needs fittings from more than one of these categories, the drawings and the certification file come from one manufacturer rather than from two sources you then have to reconcile.

Questions buyers ask before ordering

Selection and ordering questions we answer most often on this range.

What is the difference between a suspension clamp and a tension clamp?

A suspension clamp carries the cable’s weight on an intermediate pole and lets it move along its length. A tension clamp anchors the cable at the end of a span and carries the full line tension. They are not interchangeable: a suspension clamp at a dead-end will slip, and a tension clamp in mid-span will over-grip the cable.

How do I read 4x16-4x35mm² against 25-95mm²?

The first is a four-core ABC bundle with 16–35 mm² on each core; the clamp closes around the whole bundle. The second is a single insulated conductor of 25–95 mm². If your line is a four-core bundle, you need a 4x model even when the per-core section sits inside a single-conductor range.

Is a 4 kN clamp enough for an LV-ABC service drop?

For a normal service drop it is, which is why 1.1C exists at 4 kN. It is not enough wherever the drawing specifies 9 kN or more, and it is not a substitute for 1.1A on a feeder span. If your specification gives a load, match the load; if it gives only a cable size, tell us the span and we will check which rating applies.

Do I have to order the bracket separately?

Yes. PS1500L, ES1500L and CA1500 are pole brackets that carry the clamp; they are listed separately because one pole type may need a different bracket from the next. Tell us the pole and the clamp and we will pair them.

My ADSS cable is 9.5 mm. Will the Ø8-12mm clamp fit?

Yes, that is inside its range. The two 5–8 mm SHC builds will not: they are for smaller drop cable. The important number for a round cable is the outside diameter over the sheath, not the fibre count.

Can these clamps be used on bare AAAC or ACSR?

Our published ranges describe insulated ABC and round fibre cable. For bare conductor we confirm the body against the actual conductor diameter and the groove shape before quoting, because the section in mm² does not tell us the diameter.

What materials are the clamps supplied in?

Aluminium alloy and galvanised steel, with the metal hardware galvanised or stainless depending on the model. The body material for a given model is fixed by its tooling, so tell us the model and the environment (coastal, industrial, inland) and we will confirm material and finish on the drawing.

Can you produce to our drawing or under our brand?

Yes. Send the drawing or the sample, the annual quantity and the packing you need. We quote the tooling separately from the parts, so you can see what the first order carries.

Can we start with a trial order?

Yes, and most first orders are one. Three hundred to five hundred pieces split across two or three models is the usual shape: enough to fit out a pole set and test the packing, small enough that the freight does not dominate the invoice. We quote the mix as one price rather than three.

How do we compare your figure against a landed cost?

Ask for CFR or CIF to your port instead of FOB. We quote the freight leg separately, so you can see what the sea freight adds, and we send the packing list with carton dimensions and weights, which is what your broker needs to clear the shipment.

To get a quotation

Five details let us confirm the exact model rather than quote you a range and leave you to choose.

What to send

  • What the line suspends: four-core ABC, single insulated conductor, or round fibre
  • Conductor section in mm², or cable outside diameter in mm for fibre and ADSS
  • Quantity and destination port
  • The breaking load your pole design calls for, if it specifies one
  • Whether the clamp mounts directly on the pole or on a bracket

If you only have a cable size and a quantity, send those. We come back with the model, the rating and the price, not a range to choose from yourself.

What a complete enquiry looks like

“3,000 pcs suspension clamp for 4x25 mm² ABC, mid-span on 60 m poles, with PS1500L brackets, CIF Manzanillo.”

The 4x25 mm² bundle fixes the group, and the bracket tells us it is pole-mounted rather than on a crossarm, so we would quote PSP25-120 with PS1500L.
