Tension Clamps
For tension clamps, PFISTERER offers three different systems, i.e. compression dead-end clamps, bolted strain clamps, and wedge-type tension clamps. Of those three clamp systems, PFISTERER has been primarily using the hexagonal compression method and has been developing it to a high technical level since the mid-sixties. The compression clamps are made of high quality aluminium alloy and used up to 1000 kN. Clamps are available for all types of conductors. |
