Each heat-tracing tape comprises a core wire and a PTC material layer which wraps the core wire. The outer layer of each heat-tracing tape is provided with an insulating layer which is made of insulating materials and wraps the corresponding heat-tracing tape. The exterior of the insulating layer is provided with a shielding layer which is in a three-layer structure, and the shielding layer is wrapped by a flame retardant layer which is wrapped by a protection sheath. Each shielding layer comprises an aluminium-magnesium-alloy braided shielding sublayer, a tinned copper wire braided shielding sublayer and a nickel-plated copper wire braided shielding sublayer from the inside to the outside. The flame retardant layer is made of flame retardant materials, and the protection sheath is made of wear-resistant materials. The cable provided by the utility model is simple in structure, is good in electromagnetic shielding effect, and is strong in anti-interference capacity.

Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of anti-interference automatic temperature-controlled heat tracing cable, it is simple in structure, and effectiveness is good, and antijamming capability is strong.
A kind of anti-interference automatic temperature-controlled heat tracing cable the utility model proposes, comprise two heating tapes that be arranged in parallel, heating tape comprises the ptc layer of heart yearn and parcel heart yearn, heating tape skin is insulating barrier, insulating barrier is formed by the insulating material that wraps up heating tape, the skin of insulating barrier is the screen with three-decker, and the skin of screen is flame-retardant layer, and the skin of flame-retardant layer is protective coat; Wherein, screen comprises almag braid shielded sublevel, tinned wird braid shielded sublevel, nickel plated copper wire braid shielded sublevel from inside to outside successively, and flame-retardant layer is that fire proofing is made, and protective coat adopts high-abrasive material to make.
Preferably, heating tape and heart yearn thereof are cylinder.
Preferably, protective coat has oblique network, and in protective coat matrix, disperse is distributed with abrasion-proof particle.
Preferably, almag braid shielded sublevel, tinned wird braid shielded sublevel, nickel plated copper wire braid shielded sublevel are that multi-layer braided web frame is stacked to be formed.
Preferably, almag braid shielded sublevel, tinned wird braid shielded sublevel, nickel plated copper wire braid shielded sublevel fit tightly each other.
Preferably, the cross section of anti-interference automatic temperature-controlled heat tracing cable is flat.
