Product Description

Advantages of cold shrinkable cable accessories
Corrosion resistance, excellent anti-aging properties, long service life, especially the conductivity is very good, can effectively evacuate the conductor resistance, dielectric loss of insulating materials and the heat generated by the conductor resistance, which can effectively improve the service life of the product; with the characteristics of inorganic materials, resistance to galvanic corrosion, leakage traces of the electrical properties of the strong, more reliable operation; a wider range of applicable temperatures, minus 55 degrees Celsius and minus 250 degrees Celsius instantaneous can maintain a normal working condition; with good performance and good performance. Normal working condition; with good hydrophobicity, can be applied to a variety of environments, such as humidity, coastal salt spray, severe filth, etc., the products of this type of cable insulation there is also a great compression force, factors affecting the quality of power cable accessories. And the greater the interface pressure, the higher the interface insulation strength, the smaller the partial discharge; due to the presence of sustained compression force, cold-shrinkable cable accessories can also be avoided when the cable operation of thermal expansion and contraction as well as bending, flexural movement of the breathing phenomenon, which also avoids the cable and the annexes produced between the air gap within the creepage breakdown phenomenon.

1. Voltage level 
26/35 (40.5) kV 

2. Connection method 
The terminations using cold shrinkable expansion structure. When in use, pull out the support strip inside the cold shrinkable tube to shrink it. There is no need special training, and no need to use fire, convenient installation.

3. Environmental adaptability 
Cold shrinkable terminations are mainly composed of prefabricate main boday, terminal lug, cold shrinkable breakout, cold shrinkable insulating tube, phase color tube. The stress cone inside prefabricate main body and the insulating body adopt liquid silicone rubber injecting formed which has lone-term stability of lasting hold power and electric firld uniform ability. Keep a suitabke radial pressure to the cable with good property of interface, there is no creepage raise from respiration when cable runs. 

4. Material 
Prefabricate main body of cold shrinkable termination adopts high quality liquid silicone rubber, which has excellent insulation, elongation, and breakdown properties, small residual deformation after expansion. Using latest expansion equipment and expansion support tube to ensure product expand without break.
