Abstract
The invention discloses a heat-resistant anti-interference gravity cable which is composed of copper conductors, a packaging belt layer, aluminum alloy conductors, a butyronitrile insulating layer, an aluminum belt shielding layer, a zinc-coated steel belt armoring layer and a chlorosulfonated polyethylene sheath layer. Three copper conductors are arranged and are extruded at the lower half part in the packaging belt layer. The butyronitrile insulating layer is extruded outside the packaging belt layer. Nine aluminum alloy conductors are arranged and are extruded at the lower half part in the butyronitrile insulating layer. The aluminum belt shielding layer packages the butyronitrile insulating layer. The zinc-coated steel belt armoring layer packages the aluminum belt shielding layer. The heat-resistant anti-interference gravity cable has advantages of wide usage and long service life. The heat-resistant anti-interference gravity cable can be repeatedly bent for 4 million times and has high oil resistance and high flame retardance. Furthermore the heat-resistant anti-interference gravity cable has advantages of high heat resistance, high deadweight stability, high interference resistance and high drainage effect.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of heat-resistant interference gravity 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, the cable such as used in aviation, boats and ships, field of petrochemical industry, requires high all especially to the low-smoke non-halogen flame-retardant of cable, heat resistance, diamagnetic jamming performance aspect.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide the heat-resisting oil resistant gravity drainage cable that a kind of self-stability is strong, heat resistance is good.
The present invention takes following technical scheme to realize: a kind of heat-resistant interference gravity cable, it is by copper conductor, belting layer, aluminium alloy conductor, butyronitrile insulating barrier, aluminium strip screen, galvanized steel strip armour and chlorosulfonated polyethylene sheath layer composition, described copper conductor is three, be extruded in the Lower Half of belting layer inside, one deck butyronitrile insulating barrier is extruded outside described belting layer, described aluminium alloy conductor is in nine Lower Halves being extruded in described butyronitrile insulating barrier inside, outer wrapping one deck aluminium strip screen of described butyronitrile insulating barrier, outer wrapping one deck galvanized steel strip armour of described aluminium strip screen.
A copper wire drainage thread is extruded between described butyronitrile insulating barrier and aluminium strip screen.
An aluminium wire drainage thread is extruded between described aluminium strip screen and galvanized steel strip armour.
The present invention has following beneficial effect in sum: this kind of cable applications is extensive, long service life, reversed bending can be experienced and reach 4,000,000 times, have the advantages that oil resistant is fire-retardant, also have that heat resistance is good, self-stability is strong, strong interference immunity and the good advantage of drainage effect.
