Description
Technical field
This utility model relates to used in nuclear power station apparatus field, and the high-temperature resistant thin-walled low-smoke non-halogen flame-retardant in a kind of nuclear power station switch board controls cable.
Background technology
Cable is made up of conductor and the outsourcing insulating protective layer of one or more mutually insulated, and electric power or information are transferred at one the wire at another；
Under generally using environment, the requirement for cable is not the highest, but, harsh environment is compared for condition, such as, the cable in nuclear power station, cable in use arises that a lot of problem；
At conventional nuclear with controlling in cable, temperature resistant grade and flexibility (flexible) thereof for cable do not propose higher requirement, but there are the highest requirement, existing cable cannot meet concrete heatproof and installation requirement for temperature resistant grade and the flexibility thereof of its cable with controlling cable in the switch board in nuclear power station.
Utility model content
The problem existed for prior art, utility model purpose of the present utility model is to provide one to compare other cables, and the high-temperature resistant thin-walled low-smoke non-halogen flame-retardant in temperature resistant grade higher, smaller nuclear power station switch board higher, flexible controls cable.
To achieve these goals, the technical solution adopted in the utility model is:
High-temperature resistant thin-walled low-smoke non-halogen flame-retardant in a kind of nuclear power station switch board controls cable, comprising:
Conductor；
Flexible high-temperature resistant layer, described flexible high-temperature resistant layer is made up of thermoplastic polyester elastomer, is wrapped in single described conductor outside surfaces；
Sheath, described sheath is arranged at described flexible high-temperature resistant layer outer surface.
This utility model is provided with described flexible high-temperature resistant layer, it is made up of thermoplastic polyester elastomer (TPEE), and this material, possessing good thermostability, elastic, croop property and insulating properties are (equal to insulating barrier before, but the flexible high-temperature resistant layer of the application is also provided simultaneously with the effect of high-temperature resistant), so, whole cable of the present utility model can be made to compare other cables, temperature resistant grade is higher, flexible higher, smaller (material outside conductor is thinner).
As preferred version of the present utility model, also include that screen layer, described screen layer are wrapped in outside some described conductors being provided with described flexible high-temperature resistant layer, form a ring-type structure；
As preferred version of the present utility model, described conductors cross is circular, and some conductors arrange in the way of circumference array, and the effect of information transmission is more preferable.
As preferred version of the present utility model, described screen layer is made up of materials at two layers, and shield effectiveness is more preferable.
As preferred version of the present utility model, in described materials at two layers, one layer is clad aluminum foil, and the structure that another layer weaves for tinned wird, shield effectiveness is more preferable.
As preferred version of the present utility model, described sheath is made up of low-smoke non-halogen flame-retardant elastomeric material, and safe and environment-friendly performance is higher, is suitable for nuclear power station and uses environment, low-smoke non-halogen flame-retardant, and can bear radioprotective and high and low temperature environment in switch board.
The beneficial effects of the utility model are:
Compare other cables, temperature resistant grade higher, more soft, smaller (material outside conductor is thinner).
