TENSION WEDGE CLAMP


Tension fittings include tension clamps of various kinds, which are used to fix the wires and cables to the tension-tension pendants corner supports.
Clamps the load of tension wires (cables) in normal mode when exposed to wind and ice.
 
Clamps, seeing loads of tension wires and cables must provide strength sealing wires (cables) is not less than 90% of the theoretical strength of the wires (cables) on the break. And also to ensure a reliable electrical connection. Relative resistance electrical contact to the terminals where the wire (rope) is cut, should not exceed one.
 
Depending on the design and method of mounting tension clamps are divided into wedge, bolt, wedge, compressible, fang.
