Self controlled temperature tracing cable is composed of conducting polymer and two parallel metal conducting wires and insulation protecting layer. Its characteristics is the conducting polymer with a high positive temperature coefficient characteristics and parallel to each other, with heating system temperature changes automatically adjust the output power, automatic heating temperature can arbitrarily truncated or in a certain range of long use, and allows multiple cross overlap without high temperature hot and burnt into consideration.

The heater corresponding with heat system with automatic adjustment of output power, therefore not due to their own heat resistant burned, but due to the actual needs of the heat is compensated.

The low temperature starting speed, temperature uniformity, because each part can be due to the change of temperature with heat automatic adjustment;

3 easy installation, simple maintenance, all day long service, high level of automation, low operation and maintenance costs;

The safety and reliability, wide application, no pollution, long service life.
