Abstract
The invention relates to the field of equipment for nuclear power plants, in particular to a high-temperature-resistant thin-wall and low-smoke halogen-free flame-retardant control cable used in a nuclear power plant control cabinet. The high-temperature resistant thin-wall and low-smoke halogen-free flame-retardant control cable comprises a conductor, a flexible high-temperature-resistant layer and a sheath, wherein the flexible high-temperature-resistant layer is made from a thermoplastic polyester elastomer and coats the outer surface of the conductor; and the sheath is arranged on the outer surface of the flexible high-temperature-resistant layer. Compared with other cables, the high-temperature-resistant thin-wall and low-smoke halogen-free flame-retardant control cable is higher in temperature-resistant grade, softer and smaller in size.
Description
Technical field
The present invention relates to used in nuclear power station apparatus field, particularly the high-temperature resistant thin-walled low-smoke non-halogen flame-retardant control cables in a kind of Nuclear power plants housing.
Background technology
Cable is made up of the conductor of one or more mutually insulated and outsourcing insulating protective layer, and from one, electric power or information are transferred to another wire located;
Under general environment for use, the requirement for cable is not very high, but, for the environment that condition is harsher, such as, for the cable in Nuclear power plants, cable in use just there will be a lot of problem;
In conventional control cable for nuclear power station, temperature resistant grade and flexibility (flexibility) thereof for cable do not propose higher requirement, but having very high requirement with control cables for temperature resistant grade and the flexibility thereof of its cable in the housing in Nuclear power plants, existing cable cannot meet concrete heatproof and installation requirement.
Summary of the invention
For prior art Problems existing, the goal of the invention of the present invention is to provide one to compare other cables, the high-temperature resistant thin-walled low-smoke non-halogen flame-retardant control cables in the Nuclear power plants housing that temperature resistant grade is higher, flexibility is higher, size is less.
In order to realize above-mentioned purpose, the technical solution used in the present invention is:
A high-temperature resistant thin-walled low-smoke non-halogen flame-retardant control cables in Nuclear power plants housing, 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 surface;
Sheath, described sheath is arranged at described flexible high-temperature resistant layer outside surface.
The present invention is provided with described flexible high-temperature resistant layer, it is made up of thermoplastic polyester elastomer (TPEE), and this material, possesses good thermotolerance, elasticity, creep property and the insulating property (insulation layer before equaling, but the flexible high-temperature resistant layer of the application also possesses the effect of high-temperature resistant simultaneously), so, it is possible to making the whole cable of the present invention compare other cables, temperature resistant grade is higher, flexibility is higher, size less (material of conductor outside is thinner).
As the preferred version of the present invention, also comprising screen layer, described screen layer is wrapped in outside some described conductors being provided with described flexible high-temperature resistant layer, forms the structure of a ring-type;
As the preferred version of the present invention, described conductors cross is circular, and some conductors arrange in the way of circumference array, and the effect of information transmission is better.
As the preferred version of the present invention, described screen layer is made up of materials at two layers, and shield effectiveness is better.
As the preferred version of the present invention, in described materials at two layers, one layer is clad aluminum foil, the structure that another layer becomes for tinned wird braiding, and shield effectiveness is better.
As the preferred version of the present invention, described sheath is made up of low-smoke non-halogen flame-retardant elastomer material, and safety, environmental-protecting performance are higher, is applicable to Nuclear power plants environment for use, low-smoke non-halogen flame-retardant, and can bear nuclear radiation and high and low temperature environment in housing.
The invention has the beneficial effects as follows:
Comparing other cables, temperature resistant grade is higher, more soft, size less (material of conductor outside is thinner).
