Self-regulation Heating Cable

We are offering low temperature self-regulation heating cable.
40'c low temperature self-regulation heating cable(dsl2)
our company has independently developed the dual flame-retardant non-metallic pipe dedicated , with tropical, mainly used in citizen , commercial buildings sprinkler system, antifreeze and drinking water systems and insulation.effective solution to soften , deformation of non-metallic pipe in common with tropical temperatures. The product has a heating are fast , dual - flame-retardant , and automatically limit temperature , save energy , installation and operation and low cost characteristics . Applies to all non-metallic piping systems , heat tracing .
(1)product structure
1. Tinned copper conductor
2. Ptc heating layer
3. Retardant irradiated polyethylene insulation
4. Aluminum foil shield (if necessary)
5. Tin-plated metal outer shield
6. Flame retardant modified polyolefin
(2)technical parameters
1. Standard colors: black
2. Temperature range: the highest maintain temperature 40'c, maximum temperature: 85'c
the minimum construction temperature: -40'c
tinned copper wire: 7×0.42、7×0.5、19×0.32、64×0.15；
shielding layer: the outer shield of tinned copper or tinned alloy wire braided
protective insulation layer: dual flame retardant
ptc heating layer: high polymer
nominal power: (10~35)w/m, (at 10'c)
thermal stability: at 10'c to 90'c back and forth between the loop 300 times, cable heat is maintained above 95% ;
bending radius: at 20'c room temperature: 20mm; at -30'c low temperature: 35mm
insulation resistance: the cable length is 100m , the ambient temperature of 75'c , with the 2500vdc shaking table shake test one minute the insulation resistance ( between conductor and shielding) the minimum is 1200mω;
starting current: maximum instantaneous starting current in the power 0.4a/m max
using the length: single phase supply:50-150m; two-phase supply:100-300m(the use of prescribed length , can be arbitrarily cut , connect , overlap)
(3) advantage:
to solve the heating problem of the non-metallic pipe
accurate temperature control , will not overheat or bad heat , safe and reliable
uniform heating , high thermal efficiency
save energy , and pollution-free
intermittent operation of the heating start fast
small startup current, low power , the annual decay rate is low , long service life
installation , easy maintenance , low running costs
automated management
