Abstract

The utility model discloses a special control power cable for spaceflight. The special control power cable mainly includes aluminum conductors, semiconductive filling layers, nickel conductiros, wrapping tape layers, a polytetrafluoroethylene insulating layer and a chlorosulfonated polyethylene sheath layer.Seven cable cores are extruded in the wrapping tape layers. Each cable core comprises one aluminum conductor and one semiconductive filling layer coating the aluminum conductor. The wrapping tape layers are coated with the polytetrafluoroethylene insulating layer, and the polytetrafluoroethylene insulating layer is coated with the chlorosulfonated polyethylene sheath layer. The special control power cable has good corrosion resistance, dielectric property and aging resistance. The special control power cable can be used in an environment at a temperature of 150-240 DEG C in the long term, and the special power cable has a low friction coefficient. The special power cable is suitable for applying in industries such as shipping, petrochemical engineering, and the like.

Description

A kind of aviation is with controlling Special power cable

Technical field

The utility model relates to field of cables, is specifically related to a kind of aviation with controlling Special power 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 boats and ships, field of petrochemical industry, to the useful life of cable, oil resistant, the requirement of corrosion resistance and dielectric property, acid-proof alkaline aspect is all high especially, only meets the requirements, and could improve in these fields the fail safe while manufacturing.

Utility model content

For overcoming the defect of prior art, the purpose of this utility model is to provide one to have corrosion resistance and dielectric property, and the aviation of ageing-resistant advantage is with controlling Special power cable.

The utility model technical solution problem adopts following technical scheme: a kind of aviation is with controlling Special power cable, it mainly comprises aluminium conductor, semiconductive packed layer, nickel conductor, belting layer, teflon insulation layer and chlorosulfonated polyethylene sheath layer composition, described belting layer inside is extruded with seven groups of cable cores, every group of cable core is all made up of aluminium conductor and one deck semiconductive packed layer of being wrapped in outside aluminium conductor, outside described belting layer, be enclosed with one deck teflon insulation layer, outside described teflon insulation layer, be enclosed with one deck chlorosulfonated polyethylene sheath layer.

Described semiconductive packed layer inside is extruded with 8 nickel conductors.

The beneficial effects of the utility model are embodied in: the utlity model has good corrosion resistance and dielectric property, and ageing-resistant, can be long-term used in the environment of 150 ~ 240 ° of C, coefficient of friction is low, and this cable can suitablely be applied to the industry such as boats and ships, petrochemical industry.
