Product Details

This series of rubber material implement the standards of GB/T5013-2008 nominal voltage 450/750V (or below)，among, TY suit SE3,TYW suit SE4,TYH is special material for electric welding machine.

The traditional general rubber sheathed cable sheath made of natural rubber and styrene-butadiene rubber mixture, early cure easily occur when in use, the problem of cable aging poor etc.. CPE rubber compound not only physical properties can meet the standard requirements, but also has the flame retardant performance, weather resistance, the appearance of fine bright, can greatly prolong the service life of the outdoor cable.
