Abstract
The utility model discloses a silicone-rubber insulating high-temperature-resistant power cable, which comprises a silicone rubber oversheath layer. A high temperature resistant insulating cable core, a filling layer, a fireproof wrapping layer, a polyethylene separating layer and a steel wire armor layer are arranged inside the silicone rubber oversheath layer; and the high temperature resistant cable core comprises conductors, conductor insulating layers, fireproof mica layers, rubber silicone insulating layers, and protective sleeve layers. The silicone-rubber insulating high-temperature-resistant power cable of the utility model possesses good insulation and high temperature resistance effects, prevents occurrence of electric shocks, and can maintain unblocked power in a period after a fire hazard so that people can take emergent measures to fight the fire, thereby improving the service life of a cable, decreasing property and life loss, and effectively improving the reliability of cable operation.
Description
Technical field
The utility model relates to the silicone rubber insulating high-temperature-resistant power cable, especially can resistant to elevated temperatures cross-linked silicone rubber insulated power cable.
Background technology
In Modern Live, cable is ubiquitous, always uses.And cable has certain danger when electric power or information are transferred to another place from one.On the one hand, the cable that causes along with the lengthening of cable service time is aging etc., and phenomenon can make the insulation function of cable greatly reduce, and causes a lot of electric shock accidentss; On the other hand, a lot of serious electric power accidents such as catch fire have also occured in the generation of the electric power accidents such as short circuit.Thereby people's property and life security have greatly been damaged.
Summary of the invention
Problem to be solved in the utility model provides the silicone rubber insulating high-temperature-resistant power cable, can effectively play insulation and resistant to elevated temperatures effect, prevent the generation of phenomenon of getting an electric shock, and can keep the unimpeded of electric current in a period of time after fire occurs, make people can take measures promptly to put out a fire.Thereby can improve the useful life of cable, reduce the loss of people's property and life, effectively improve the cable reliability of operation.
In order to address the above problem, the utility model is achieved through the following technical solutions:
The utility model silicone rubber insulating high-temperature-resistant power cable comprises the silicon rubber external sheath layer, is provided with successively from inside to outside high-temperature insulation core, packed layer, fire-resistant lapping layer, polyethylene isolation layer and wire armoring layer in the silicon rubber external sheath layer.
Further improvement of the utility model is: high-temperature insulation core and packed layer twisting stranding, the peripheral coiling twining package tape of high-temperature insulation core and packed layer forms fire-resistant lapping layer, wrapped polyethylene isolation layer outside fire-resistant lapping layer.
Further improvement of the utility model is: at the armoured steel wire of polyethylene isolation layer, form the wire armoring layer, extrude the silicon rubber oversheath outside the wire armoring layer, form the silicon rubber external sheath layer.
Further improvement of the utility model is: the high-temperature insulation core comprises and is provided with successively from inside to outside conductor, insulating layer of conductor, the fireproof mica layer, silicone rubber insulation layer, metal is dredged around screen and external sheath layer, the silicone rubber insulation layer twisting has described metal to dredge around screen, dredges at metal and extrude the formation external sheath layer outside screen.
Further improvement of the utility model is: at least one of high-temperature insulation core.
Compared with prior art, the utility model has guaranteed insulation and the resistant to elevated temperatures effect of cable from structure, prevents the generation of phenomenon of getting an electric shock, and can keep the unimpeded of electric power in a period of time after fire occurs, and makes people's urgent fire fighting of can taking measures.Thereby improved the useful life of cable, reduced the loss of people's property and life, effectively improved the cable reliability of operation.
