Abstract

The invention discloses a self temperature control heating cable, which is formed by a filling layer, a wrapping belt layer, a copper belt armor layer, a nickel belt shielding layer, a butyronitrile insulation layer, a nonmagnetic metal armor layer and a neoprene rubber sheath layer; the filling layer is used as the central layer of the cable and is wrapped by one layer of wrapping belt layer; one layer of copper belt armor layer wraps the wrapping belt layer and is wrapped by one layer of nickel belt shielding layer; one layer of butyronitrile insulation layer wraps the nickel belt shielding layer; one layer nonmagnetic metal armor layer wraps the butyronitrile insulation layer. The cable is strong in bending resistance, good in cooling effect, high-temperature resistant, low-temperature resistant, and convenient to transport and has the advantages of strong oxidation resistance, strong tensile resistance and low paving environment temperature.

Description

A kind of self controlled heating cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of self controlled heating cable.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the field such as computer, machine room, high and low temperature resistance to cable, pull resistance, thermal diffusivity, cold-resistant high temperature resistant and non-oxidizability aspect require all high especially.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one high temperature resistant, cold-resistant, non-oxidizability is strong, lays the self controlled heating cable that temperature environment is low.

The present invention takes following technical scheme to realize: a kind of self controlled heating cable, it is by packed layer, belting layer, copper strips armour, nickel strap screen, butyronitrile insulating barrier, nonmagnetic metal armour and chloroprene rubber sheath layer composition, described packed layer is as the central core of this cable, outside described packed layer, wrap up one deck belting layer, outside described belting layer, wrap up one deck copper strips armour, outside described copper strips armour, wrap up one deck nickel strap screen, outside described nickel strap screen, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up one deck nonmagnetic metal armour, described nickel strap screen inside is provided with 16 copper conductors, described butyronitrile insulating barrier inside is provided with 24 copper conductors.

The present invention has following beneficial effect in sum: this kind of cable resistance to bend(ing) is strong, and good heat dissipation effect is high temperature resistant, cold-resistant, and convenient transport also has non-oxidizability strong simultaneously, and pull resistance is strong, lays the advantage that temperature environment is low.
