Product Description

Technical Parameter

The body and keeper are made of malleable iron, the cotter pin is made of stainless steel, other parts are made of hot-dip galvanized steel.

Tin-plated copper alloy blades imbaedded in molded plastic and surrounded with a sealing compound insure electrical contact in 1KV or 10KV overhead distribution networks. A single or double torque-control nut draw the two halves of the connector together and shears off when the teeth have pierced the insulation and made contact with the conductor strands.

Electric performance: expanded wire range rate of the resistance is lower than 2.5

Mechanical performance: the connector has no crack when the lead is broken by pulling

Temperature rise performance: under the condition of big current, the temperature rise the connector is less than the connection lead

Heat circle performance: 200timers per second, 100A/mm2 big current overload, the change of the connection resistance is less than 5%

Water proof performance: resistant to 6kv1minute after 30minutes immersion in water

Fire proof performance: V0 fireproof

Resistance to corrosion: under the condition of SO2 and salt fog the connector can do three times of 14days circle test.

Environment aging performance: under the circumstance of ultraviolet radiation, dry and moist, expose it with change of temperature and heat impulse for 6weeks.
