Internal wiring port section of the heating tube does not adopt the terminal connection mode,
Making it havhigh temperature resistance and strong mechanical properties.
The port part of the heating tube adopts terminal connection mode Is resistant to
high temperature and works in the heating medium which can not conduct wiring at both ends.
