Insulation piercing connector is mainly suitable for the connection of the overhead insulation conductor, branch connection and grounding protection, It is used for the voltage which is 20KV, 10KV and 1KV and below. Applicable for Al-Cu conductor, different diameter wire connection, and equal diameter wire butt, and is suitable for the transition of copper aluminum insulation conductor link. 

General of insulation piercing connector(lPC) 
1.1 Piercing connector, simple installation, need not strip the cable coat. 
1.2 Moment nut, piercing pressure is constant, keep good electrìc connection and make no damage to lead 
1.3 Self-seam frame,wetproof, waterproof,and anti-corrosion, extend the using life of insulated lead and connector 
1.4 Adopted special connectìng tablet, apply to joint of Cu(Al) and Cu(Al) or Cu and Al 
1.5 Small electric connecting resistance, connecting resistance less than 1.1 tìmes of the resistance of branch conductor wìth the same length
1.6 Special insulated case body, resistance to illuminatìon and environmental aging, the insulation strength can up to 12KV 
1. 7 Arc surface design,apply to connection with the same(different) diameter, wide connection scope(0.75mm2-400mm2)
(Performance testing) 
2.1 Mechanical performance:the grip force of the wire clamp is 1/10 bigger than the break force of the lead. It comply with GB2314-1997 
2.2 Temperature rise performance: under the conditìon of big current, the temperature rise of connector is less than that of connection lead.
2.3 Heat circle performance:confirms to GB/T2317.3-2000,the beat circle trial standard for electric fitting. 
2.4 Waterproof insulatìon performance:confirms to the relevant requirements in Part 2 of GB/TI3140.4-1998, 
2.5 Resistance to corrosion performance: under the conditìon of SO, and salt fog, it can do three tìmes of fourteen days circle testìng. 
2.6 Environmental aging performance:under the circumstance of ultraviolet, radiation, dry and moist, expose if with change of temperature and beat impulse for six weeks. 
2.7 Fire-proof performance: insulation material of the connector withstands glowing filament test. Confirm to the requirements in Chapter4-1 0 of GBrr5169.4
