Construction Of The Inner Wedge Material Of The Wedge-shaped Tension Clamp

The inner wedge of the dead end clamp for ab cable is made of weather-resistant, insulating, reinforced engineering plastic. This plastic is resistant to ultraviolet radiation and weathering, and can withstand long-term outdoor environmental changes—rain, sunlight, temperature differences, humidity, etc. Even when the line is laid in harsh environments such as humid, high-temperature, or coastal areas, the plastic inner wedge maintains its structural integrity and insulation.

The inner wedge's matching design with the dead end clamp for abc cable shell ensures smooth sliding under tensile force, providing appropriate clamping pressure to the conductor. The clamping process will not damage the conductor or its insulation layer, and the contact surface between the plastic wedge and the conductor sheath is smooth.

The fungsi dead end clamp inner wedge has undergone an AC withstand voltage test of 45kV, maintaining the voltage for 1 minute without breakdown or flashover.
