D / Z / GWL-CT self-controlling temperature heating cable PF46 / PFA self-limiting temperature heating cable

Information source: Anhui Cable Group Views: 6239 Release time: 2014-04-15

I. Overview
D / Z / GWL-CT self-controlling temperature heating cable ( self-limiting electric heating cable) is divided into three types, DWL-CT is a low-temperature series self-controlling temperature heating cable, and ZWL-CT is a medium-temperature series self-controlling temperature heating cable Tropical, GWL-CT is a high series of self-controlling temperature and electric heating cable; CT is anti-corrosion reinforced, and the outer sheath uses imported raw materials of PF46 or PFA.

D / Z / GWL-CT self-controlling temperature heating cable (self-limiting temperature heating cable) structure is composed of two parallel wires in a conductive polymer heating core. The heating core is radiation-crosslinked to ensure durability and can be automatically The output power is adjusted to compensate for temperature changes, and heat is generated when current passes through the conductive polymer core between the conductors.
The coverage of the braided layer of tinned copper wire reaches 85%, which can better play the role of explosion protection and resistance to external forces, and better shielding effect. The outer sheath is made of PF46 and PFA imported materials, which greatly improves the anti-corrosion and explosion-proof performance, and can withstand temperatures above 180 ° C. It is truly a product comparable to imported electric heating cables . It is suitable for dangerous places with special requirements, and it is also suitable for homes, large buildings and industrial applications.
