Piercing tap connector N640 16-150 mm2 / 6-50 mm2 (ABC/bare wire) EKF n-640

The n-640 type clamp is designed to create a sealed electrical connection between an insulated SIP wire and an uninsulated overhead line main wire. Contact with the insulated wire is ensured by piercing the insulation, and with the uninsulated wire by a clamping plate. Once the torque required to create a reliable electrical contact between the wires is reached, the bolt head snaps off. The contact plates are made of tinned aluminum alloy. Contact grease is applied to the piercing elements. The bolt is insulated from the contact parts of the clamp. The clamp is resistant to ultraviolet and solar radiation, high and low temperatures, corrosion, and aggressive atmospheric effects.
