CN201898632U - Automatically-temperature-controlled heating cable - Google Patents

Abstract

The utility model discloses an automatically-temperature-controlled heating cable, which comprises a plurality of buses and automatically-temperature-controlled conducting cable cores. The automatically-temperature-controlled conducting cable cores are wrapped outside the buses, an insulating layer, a shielding layer, an armor layer and a sheath layer are sequentially wrapped outside each automatically-temperature-controlled cable core, the insulating layers are made of thermoplastic elastomers or fluorine compounds, and the shielding layers are formed by weaving stainless steel wires or tinned copper wires. The automatically-temperature-controlled heating cable is simple in structure and fine in shielding performance and enhances mechanical performance by adding the armor layers among the shielding layers and the sheath layers, and the service life of the cable is effectively prolonged.

Description

A kind of self controlled heating cable

Technical field:

The utility model relates to the heating cable field, specifically is a kind of self controlled heating cable.

Background technology:

Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.

Self controlled heating cable is a kind of special type heating temperature control cable that can change automatic adjustment heating power with temperature environment, have automatic heating and temperature control dual-use function, the core component of self controlled heating cable---adopt the core of the good flat of the long-term serviceability of process from the temperature control conductor wire core, it is more superior to compare traditional stability from temperature control conductor wire core temperature control, increase armour simultaneously, increased mechanical performance.

The utility model content:

The purpose of this utility model provides a kind of self controlled heating cable that is used for companion's heat such as pipe flange, valve, joint or suspension bracket, has solved traditional defective from temperature control accompanying-heat cable control temperature stability difference, has strengthened mechanical performance simultaneously.

Technical scheme of the present utility model is as follows:

A kind of self controlled heating cable, comprise several buses, from the temperature control conductor wire core, described several buses outside is enclosed with from the temperature control conductor wire core, it is characterized in that: described insulating barrier, screen, armour, the restrictive coating of being enclosed with successively outside the temperature control conductor wire core.

Described self controlled heating cable is characterized in that: described insulating layer material is thermoplastic elastomer (TPE) or fluorine compounds, and described screen adopts stainless steel wire or tinned copper wire braiding to form.

The utility model has the advantages that:

The utility model is simple in structure, and shielding properties is good, has increased armour between screen and restrictive coating, mechanical performance arrived raising, effectively prolonged the useful life of cable.

Description of drawings:

Fig. 1 is the utility model structural representation.

Embodiment:

A kind of self controlled heating cable, comprise several buses 1, from temperature control conductor wire core 2, several buses 1 outside is enclosed with from temperature control conductor wire core 2, from temperature control conductor wire core 2 is the flat structure, outside temperature control conductor wire core 2, be enclosed with insulating barrier 3, screen 4, armour 5, restrictive coating 6 successively, insulating layer material is thermoplastic elastomer (TPE) or fluorine compounds, and screen 4 adopts stainless steel wire or tinned copper wire braiding to form.
