Abstract
The invention discloses an anti-magnetic acid and alkali-resistant cable. The cable is composed of aluminum alloy cable cores, a low-smoke halogen-free polyolefin sheath layer, a teflon insulating layer, a carbon fiber belt layer, an aluminum belt armored layer and aluminum conductor cable cores. The three aluminum alloy cable cores are extruded inside the low-smoke halogen-free polyolefin sheath layer, the low-smoke halogen-free polyolefin sheath layer is externally extruded by the teflon insulating layer, the teflon insulating layer is externally wrapped by the carbon fiber belt layer, and the carbon fiber belt layer is externally wrapped by the aluminum belt armored layer. The cable provided by the invention is wide in purposes, long in service life, high in acid and alkali resistance and high in anti-magnetic-interference performance, can be bent in a cyclic manner by one million times, and also has the advantages of good cold resistance and excellent waterproof and oil resistance performance.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of antimagnetic acid and alkali-resistance 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, cold tolerance and waterproof oil resistance aspect.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of low-smoke non-halogen flame-retardant, antimagnetic acid and alkali-resistance cable that cold tolerance is good.
The present invention takes following technical scheme to realize: a kind of antimagnetic acid and alkali-resistance cable, it is made up of aluminium alloy cable core, low-smoke halogen-free polyolefin restrictive coating, teflon insulation layer, carbon fiber belt, aluminium strip armour and aluminium conductor cable core, described aluminium alloy cable core is three groups, be extruded in low-smoke halogen-free polyolefin restrictive coating inner, one deck teflon insulation layer is extruded with outside described low-smoke halogen-free polyolefin restrictive coating, outer wrapping one deck carbon fiber belt of described teflon insulation layer, wraps up one deck aluminium strip armour outside described carbon fiber belt.
Low-smoke halogen-free polyolefin restrictive coating inner homogeneous is extruded with three groups of aluminium conductor cable cores.
The present invention has following beneficial effect in sum: this kind of cable applications is extensive, and long service life, has the feature of acid and alkali-resistance, diamagnetic interference, can experience reversed bending and reach 1,000,000 times, also have the feature that cold tolerance is good and waterproof oil resistance is excellent.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, aluminium alloy cable core; 2, low-smoke halogen-free polyolefin restrictive coating; 3, teflon insulation layer; 4, carbon fiber belt; 5, aluminium strip armour; 6, aluminium conductor cable core.
Embodiment
As shown in Figure 1, a kind of antimagnetic acid and alkali-resistance cable, it is made up of aluminium alloy cable core 1, low-smoke halogen-free polyolefin restrictive coating 2, teflon insulation layer 3, carbon fiber belt 4, aluminium strip armour 5 and aluminium conductor cable core 6, described aluminium alloy cable core 1 is three groups, be extruded in low-smoke halogen-free polyolefin restrictive coating 2 inner, one deck teflon insulation layer 3 is extruded with outside described low-smoke halogen-free polyolefin restrictive coating 2, outer wrapping one deck carbon fiber belt 4 of described teflon insulation layer 3, outer wrapping one deck aluminium strip armour 5 of described carbon fiber belt 4.
Low-smoke halogen-free polyolefin restrictive coating 2 inner homogeneous is extruded with three groups of aluminium conductor cable cores 6.
This cable allows operational environment maximum temperature to be 70 DEG C; The permission bending radius of this cable is 8 times of the outside diameter of cable.
The above is embodiments of the invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
