Designed for fastening SIP-3 wire with a voltage of 6–20 kV on an intermediate pole. Specifications: The PSM 25-150 support clamp is made of reinforced aluminum alloy coated with a dielectric material. Wire installation is performed without stripping the insulation and without the use of special tools. To equalize the potential of the wire and the insulator end, the clamps are supplied with a R 645 airtight piercing clamp and an insulated flexible conductor. The PSM 25-150S clamp is equipped with an eyelet for attachment to a glass or polymer insulator with a plunger-type end.
