Description
Feature of product:
Technique of full cold shrink:
Without fire work and special tools, simply pull the wick gently, will retract
rely on its own elasticity, so attaches to the cable closely, each specification
can be applied to a variety of cable diameter, strong compatibility with cable
diameter.
Reliability of insulation:
Using liquid silicone rubber to ensure good insulation and high elasticity.
Always maintain constant radial pressure on cable body after installation,
insulation main body of product and electrical stress control unit preform
as a whole in factory, little partial discharge capacity, "breathing" with cable
body simultaneously.
Stable performance:
Supporting tube using ultrasonic welding, to ensure the reliability and
stability of the products, permanent tensile and lower deformation rate,
improve the warranty period of products.
Reliable sealing:
The terminal body coordinate with cold shrink branch finger sleeve, cold
shrink insulation pipe and cold shrink terminal seal tube; The intermediate
joint kits adopt with three layer of waterproof sealing technology, to ensure
excellent seal moisture performance of accessories.
Easy for installation:
Simple installation, convenient operation, easy to master. Stripping distance
is short and installation space demand is little while pretreatment of cable.
Grounding method by using constant force spring to fix the earth lead
without welding or tied copper wire, and one end of the ground has been
compressed with terminal, more convenient installation, safe and reliable.
Widely Use:
Pollution resistance, ageing resistance, good hydrophobic, and have
excellent corrosion resistance, cold resistance and resistance to ultraviolet
ray, to ensure the long-term and stable performance usage. Especially
suitable for high altitude, cold, damp, salt fog and heavy pollution areas
