General of Insulation piercing connector

• Piercing connector,simple installation,need not strip the cable coat
• Moment nut,piercing pressure is constant,keep good electric connection and make no damage to lead
• Self-seam frame,wetproof,waterproof,and anti corrosion,extend the using life of insulated lead and connector
• Adopted special connecting tablet apply to joint of Cu(AI) and AI
• Small electric connecting resistance,impulse current can be up to 15KA
• Special insulated case body, resistance to illumination and environment aging,the insulation strength can up to 6KV.Arc surface design,apply to connection with the same (different) diameter,wide connection scope(1.5-240mm2)

Performance Testing

• Mechanical performance:the gri force of the wire clamp is 1/10 bigger than the break force of the break force of the lead.It comply with GB2314-1997
• Temperature rise performance:Lunder the condition of big current,the temperature rise of connector is less than that of connection lead
• Heat circle performance:200 times per scond,100A/mm2 big current,overload,the change of connection resistance is less than 5%
• Wetproof insulation performance:under the connection of SO2 and salt fog,it can do three times of fourteen days circle testing.
• Environmental aging performance:under the circumstance of ultraviolet,radiation,dry and moist,expose it with change of temperature and heat impulse for six weeks.

Installation Piercing Connectors

 The reason of choosing insulation piercing connector

• Simple installation

   Can be branch of cable without striping the insulatd coat and the joint is completely insulated,make brance in the random lacation of cable without sutting 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 30years

• 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 sysyem.
