Insulation Piercing Connectors
General of insulation piercing connector(IPC)
1.Piercing connector, simple installation, need not strip the cable coat
2.Moment nut, piercing pressure is constant, keep good electric connection and make no damage to lead
3.Self-seam frame, wetproof, waterproof, and anti-corrosion, extend the using life of insulated lead and connector
4.Adopted special connecting tablet, apply to joint of Cu(Al) and Cu(Al) or Cu and Al
5.Small electric connecting resistance, connecting resistance less than 1.1 times of the resistance of branch conductor with the same length
6.Special insulated case body, resistandce to illumination and environmental aging, the insulation strength can up to 12KV
7.Arc surface design, apply to connection with the same(different) diameter, wide connection scope(0.75mm2~400mm2)
(Performance testing)
1.Mechanical performance: the grip force of the wire clamp is 1/10 bigger than the break force of the lead. It comply with GB 2314-1997
2.Temperature rise performance: under the condition of big current, the temperature rise of connector is less than that of connection lead
3.Heat circle performance: conforms to GB/T 2317.3-2000, the heat circle trial standard for electric fitting
4.Waterproof insulation performance: conforms to the relevant requirements in Part 2 of GB/T 13140.4-1998
5.Resistance to corrosion performance: under the condition of SO2 and salt fog, it can do three times of fourteen days circle testing
6.Environmental aging performance: under the circumstance of ultraviolet, radiation, dry and moist, expose if with change of temperature and heat impulse for six weeks
7.Fire-proof performance: insulation material of the connector withstands glowing filament test. Conform to the requirements in Chapter 4-10 of GB/T 5169.4
Th e reason of choosing insulation piecring connector (IPC)
Simple installation
Con be branch of cable without striping the insulated coat and the joint is completely insulated. Make branch in the random location of cable without cutting off the main cable. Simple and reliable installation, just need sleeve spanner, can be installed with on live line.
Safe use
The joint has good resistance to distortion, quake, fire, wet, electrochemical corrosion and aging, need no maintenance. Has been used successfully for 30 years.
Economical cost
Small installation space, save the cost of bridge and land construction. In structural application, there need no terminal box, junction box and return wire of cable, save cable cost. The cost of cables and clamps is lower than other power supply system.

Insulated piercing connector
Material: High strength aluminium alloy, anti-UV plastic
A broad usage in the low voltage insulation lines, leading the branch connection to the main conductor. T-connection of low voltage insulation wtre service and cable branch connection for building distribution system. The material for the inside body is high strength aluminum alloy, and the insulation cover is used polyvinyl chloride(PVC). The connectors with specially designed contact teeth, are suitable for the connection of aluminum. Put the main conductor and branch conductor parallel into the teeth grooves of the clamp, tighten the bolts, pierce the insulation of two conductors to make the conductors connect.
The insulation cover functions as waterproof and sealing perfectly.
At the breaking force of the conductor, the connector will not be distorted and broken. At the rated current and short circuit, rising temperature of the connector should be less than the connecting conductor.
