Abstract
The invention discloses a rated voltage variable frequency cable, which is formed by three groups of aluminum alloy cable cores, a silicon rubber insulation layer, three groups of copper cable cores, an aluminum belt armor layer, a galvanized steel belt armor layer and a low smoke zero halogen polyolefin sheath layer; the aluminum alloy cable cores and the copper cable cores are extruded and wrapped in the silicon rubber insulation layer; one layer of aluminum belt armor layer wraps the silicon rubber insulation layer and is wrapped by one layer of galvanized steel belt armor layer. The rated voltage variable frequency cable is widely used in the fields such as power generation, aviation, ship, chemical industry and petroleum, and has the advantages of excellent insulation performance, excellent high-temperature resistant and fireproof performances, aging resistance, acid-base resistance and corrosion resistance.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of rated voltage frequency-changing cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as generating, aviation boats and ships, chemical petroleum, to the fire resistant of cable, acid and alkali-resistance, the requirement of corrosion resistant aspect is all high especially, only meets the requirements, and could improve in these fields the fail safe while manufacturing.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one ageing-resistant, acid and alkali-resistance, corrosion resistant rated voltage frequency-changing cable.
The present invention takes following technical scheme to realize: a kind of rated voltage frequency-changing cable, it is made up of aluminium alloy cable core, silicone rubber insulation layer, copper cable core, aluminium strip armour, galvanized steel strip armour and low-smoke halogen-free polyolefin sheath, described silicone rubber insulation layer inside is extruded with three group aluminum alloy cable cores and three groups of copper cable cores, described silicone rubber insulation layer is wrapped with one deck aluminium strip armour, and described aluminium strip armour is wrapped with one deck galvanized steel strip armour.
Described aluminium alloy cable core is made up of three group aluminum alloy cores and the teflon insulation layer that is wrapped in outside aluminium alloy core.
The present invention has following beneficial effect in sum: the present invention is widely used in the fields such as generating, aviation boats and ships, chemical petroleum, there is good insulation property and good fire resistant performance, also have simultaneously ageing-resistant, acid and alkali-resistance, corrosion resistant advantage.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
