Product Features

Features of the NES-B1 4 Core Electrical Tension Clamp

Material：The main body is made of thickened die-cast aluminium alloy with a weather-resistant, non-slip engineering plastic lining, providing ample load-bearing capacity and ensuring the insulation sheath of the four-core cable is not damaged during clamping.

Manufacturing Process：Utilising an integrated die-casting process with a four-chamber independent positioning structure and a self-locking, bolt-free assembly method, it ensures even force distribution and enables efficient and convenient on-site installation.

Corrosion Protection：The aluminium housing undergoes anodised protection treatment, whilst the internal elastic metal components are treated to prevent rust. This enables the product to withstand exposure to sunlight and rain outdoors, ensuring it remains rust-free and secure even during long-term outdoor use.

Standards：Suitable for 1 kV voltage-rated 4×16–70 mm² four-core bundled cables, with a rated tensile load of 20 kN. Complies with the specifications for fittings used in low-voltage overhead distribution lines entering residential premises.
