Abstract

The invention discloses a novel heating cable. The novel heating cable is characterized by adopting a circular structure with side wings; heating alloy wires 1, a non-heating lead 2, a first insulating layer, a second insulating layer 4, over-temperature protection temperature sensors and leading wires 5, a first shielding layer 6, a second shielding layer serving as a ground wire 7, a protective sheath 8 are arranged inside the novel heating cable; a single-conductor structure and a double-conductor structure are arranged inside the novel heating cable; the double-conductor structure comprises two modes: in one mode, a heating alloy wire 1 and a non-heating lead 2 are arranged, in the other mode, two heating alloy wires 1 are arranged; a plurality of over-temperature protection temperature sensors and leading wires 5 are available; the second shielding layer serving as the ground wire 7 extends to two sides; and the protective sheath 8 is arranged outside the second shielding layer serving as the ground wire 7 for protecting the second shielding layer serving as the ground wire 7, so as to form two side wings 9.

Description

A kind of novel heating cable

Technical field:

The present invention is a kind of novel heating cable, belongs to heating cable equipment.

Background technology:

In current heating cable; its structure is mainly with the heating line; the individual layer insulation; single-layer shield is main; its insulation; shield effectiveness is good inadequately; insufficient strength is good; and heat transfer rate is slow; in work progress, also to lay the overheat protector temperature transducer in addition; the work progress complexity; and because the job location area is big; the overheat protector temperature transducer is layouted few; do not have the effect of overheat protector; and because the overheat protector temperature transducer seals in work progress and does the failure rate height well, can not repair in case damage, do not substitute; exist insulation in the current heating cable construction; shield effectiveness is good inadequately; insufficient strength is good; heat transfer rate is slow, the phenomenon that overheat protector is bad.

Summary of the invention:

The present invention's " a kind of novel heating cable " has solved the problems referred to above of present existence; this heating cable has two-layer insulation, two-layer shielding; and have that flank is gained in strength and radiating effect; it can be single guide structure; also can be two guide structures; also a plurality of overheat protector temperature transducers and heating cable are combined, realize that point protection to the upgrading of face protection, reduces difficulty of construction.

The invention has the beneficial effects as follows; can strengthen the insulation effect of heating cable, ensure and use safety, strengthen shield effectiveness; guarantee does not have the harm of electromagnetic radiation; strengthen intensity, strengthen useful life, accelerate heat transfer rate; make indoor intensification rapid; effectively solve the problem of arranging overheat protector temperature transducer difficulty in the heating cable construction, realize the protection of heating cable multiple spot face, use more safe and reliable.

The technical solution adopted in the present invention is: this a kind of novel heating cable is circular band flank structure; there is heating alloy silk inside; heating-wire not; the ground floor insulation; second layer insulation; the ground floor shielding; the double ground wire of second layer shielding; overheat protector temperature transducer and lead-in wire; the protection crust; it can be single guide structure of a heating alloy silk; in single guide structure; having not at the two ends of heating cable, heating-wire links to each other with heating alloy silk; also can be that a heating alloy silk adds not two guide structures of heating-wire or two heating alloy silks; in two guide structures; having not at an end of heating cable, heating-wire links to each other with heating alloy silk; the other end will generate heat that the alloy silk links to each other with heating-wire not or two heating alloy silks will be linked to each other; the overheat protector temperature transducer can arrange a plurality of; caused an end of heating cable by lead-in wire; be connected with thermostat or control circuit and get final product; the double ground wire of second layer shielding extends to both sides, and the protection of protection crust is arranged outward, forms two flanks.
