Aluminum Alloy Bolted Type Dead End Tension Clamp for Distribution Line
Tension clamps are used to fix conductor and ground wire through insulators or link fitting to tower arms or substation structrues.In according to the clamp construction and mounting way,the clamps include three types as compression type, bolt type and wedge type.The compression type include hydraulic type and explosive type.
1. Strain clamps fix conductors and ground wires through insulators or link fittngs to tower arms or substation structures.
2. According to the aluminum alloy strain clamps construction and mounting way, the aluminum alloy strain clamps include two types: compression type and bolt type.
3. The Aluminum Alloy Strain Clamps (Compression Type ) include Hydraulic and explosive type.
4. As the Bolt Type Aluminum Alloy Strain Clamps are used to AAC and ACSR, the conductor may to wound by aluminum tapes or preformed armour rods for protecing these taps or rods are included in the diameter of suitable conductor.
