1,Product Description
* Strain clamps fix conductors and ground wires through insulators or link fittngs to tower arms or substation structures.
* According to the aluminum alloy strain clamps construction and mounting way, the aluminum alloy strain clamps include two types: compression type and bolt type.
* The Aluminum Alloy Strain Clamps (Compression Type ) include Hydraulic and explosive type.
* As the Bolt Type Aluminum Alloy Strain Clamps are used to AAC and ACSR, the conductor mayto wound by aluminum tapes or preformed armour rods for protecing these taps or rods are
included in the diameter of suitable conductor.
Structure Feature
* The body is made of high-strength aluminium alloy
* Smooth surface long servile life
* Easy installation
* No waste electric energy
Insulation Cover Performance Feature
