15-39mm Max Open Insulated Conductor Gripper Come Along Clamp with Parallel Non-Slip Jaw and Aluminium Alloy Body

What this gripper is built to do

Insulated overhead conductor cannot be treated like bare wire. Strip the sheath to get a metal-to-metal grip and the conductor is compromised at the very point where it will spend its service life bending in wind. The SKJL gripper answers that with a jaw set that closes on the outside of the insulation, so the pulling load is taken through the sheath and the conductor underneath stays untouched.

The series covers a maximum open of 15mm to 39mm with a rated load band of 10KN to 30KN, which puts it in the range of medium voltage distribution stringing and service work rather than transmission pulls.

Series parameters on record

Reading a load band instead of a single number

The 10-30KN band describes the series, not one clamp. When a project asks for a rated load, quote the figure for the specific opening size being ordered, and match it against the calculated tension for the section rather than the winch capacity. A clamp chosen at the top of its opening range spends its life near the end of the jaw travel, where the geometry is least forgiving.

Clamping over insulation

Three habits keep an insulated grip honest. Clean the sheath first, because grit under the jaw is what scores the surface. Set the jaw across the full contact length instead of letting the cable sit at one edge. And never leave a clamp parked on a tensioned insulated conductor for longer than the pull requires: creep under sustained load is the usual cause of a sheath that looks fine on installation and fails an inspection two seasons later.

Dispatch checks

• Jaw faces inspected for burrs and for liner damage before packing.
• Open and close travel checked across the full 15-39mm range.
• Body marked with the model and load band.
• Plywood case packing, 500 PCS per month supply capacity.

What this page does and does not say

The parameters above come from the current SKJL catalogue entry. This page does not publish a weight saving percentage against steel clamps, does not claim compatibility with every insulated conductor type on the market, and does not name a certification beyond the ISO entry in the attribute table. Where a utility specification calls for a proof load test, ask for it with the enquiry and we will confirm what can be supplied.

Questions we are asked

Will it damage the insulation?

The jaw closes on the sheath with a parallel contact face rather than a cutting tooth profile. Sheath condition still depends on correct use: clean surface, full jaw contact, no long term parking under load.

Which size should I order?

Measure the outside diameter of the insulated conductor, add margin for sheath tolerance, and choose the clamp whose opening covers that figure comfortably.

Can it pull bare conductor too?

This series is specified for insulated conductor. For bare wire use a gripper with a hardened toothed jaw sized to the strand diameter.
