TTD Series Fire-retardant Insulation Piercing Connectors

1.Used for branch connection of insulated cable for building distribution system,connection of LV overhead insulated cables,branch connection of LV insulated service-entrance able,distribution system of streelight,etc.
2.Main line: insulated copper or aluminium;
3.Branch line: insulated copper or aluminium;
4.Live-line work or power-cut work is allowable;
5.Main body of connector is made of high strength insulating material that anti mechanical change or climatic variation.
6.The screw that is equipped with fastening torque nut is anti-corrosion treated,the torque nut enables the installion to be much simple,safe and quick,its constant puncturing pressure guarantees best electrical effect for the cable connection.
7.The connector is featured with property of waterproof,it is able to withstand voltage of 6kV in water without breakdown
phenomenon.
8.The waterproof sealing end cap of branch line prevents water from entering into the branch connected conductor.It can be
branched on the left or right side according to the demand.

1.Mechanical performance:the grip force of the wire clamp is 1/10 bigger than the break force of the lead,which comply the GB2314-1997 standard.
2.Temperature rise performance:under the condition of strong current,the temperature rise of connector is less than that of
connection lead.
3.Heat circle performance:conforms to GB/T2317.3-2000,the heat circle trial standard for electric fitting.
4.Waterproof insulation performance:conforms to the rlevant test requirements in Part 2 of GB/T13140.4-1998.
5.Resistance to corrosion performance: under the condition of SO2 and salt fog,it can do three times of fourteen days circle test.
6.Environment aging performance: under the circumstance of ultraviolet,radiation,dry and moist,expose it with change of temperature and heat impulse for six weeks.
7.Fire-proof performance: insulation material of the connector with stands glowing filament test.Conforms to the requirements
in Chapter 4-10 of GB/T5169.4.
