Description
Technical field
The utility model belongs to power cable technical field, is specifically related to a kind of fluoroplastic insulation type control cables.
Background technology
Along with the fast development of China's economy, as carrying the main tool cable transmitting with signal also to obtain effective development, the cable of prior art is mainly made up of restrictive coating, conductor, screen and flame retardant coating, although it can effectively play shielding and fire-resistant function, but smelt and the industry such as petrochemical industry because its temperature is higher, corrosivity is stronger, can affect to a certain extent the useful life of cable, also can affect to a certain extent the stability in use of cable, be difficult to meet the needs in market simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, stability in use good and high temperature resistant with the strong fluoroplastic insulation type control cables of decay resistance.
The technical scheme that realizes the utility model object is a kind of fluoroplastic insulation type control cables, comprise total restrictive coating, be arranged on the conductor in described total restrictive coating, described conductor is four, the skin of described conductor is provided with screen, insulating barrier and flame retardant coating, in described total restrictive coating, be provided with total flame retardant coating and total screen, between described total screen and described flame retardant coating, be provided with external extension annulus and interior flexible annulus, on described external extension annulus and described interior flexible annulus, be equipped with adjusting vertical slot, between described external extension annulus and described interior flexible annulus, be provided with temperature expansion protection body, described external extension annulus and described total screen connect, described interior flexible annulus and described flame retardant coating connect, between described external extension annulus and described total screen, be provided with outer lateral adjustments little spring, between described interior flexible annulus and described flame retardant coating, be provided with interior lateral adjustments small pressure spring.
Be provided with elasticity packed layer at the center of described total restrictive coating.
In described elasticity packed layer, be provided with small ventilating holes.
On the outer wall of described conductor, be provided with tin coating.
The utlity model has positive effect: of the present utility model simple in structure, easy to use, in total restrictive coating, be provided with interior flexible annulus and external extension annulus, and be provided with temperature expansion protection body between interior flexible annulus and external extension annulus, and between interior flexible annulus and flame retardant coating, be provided with interior lateral adjustments small pressure spring, between external extension annulus and total screen, be provided with outer lateral adjustments little spring, when use, in the time that temperature is higher, temperature expansion protection body temperature-sensitive also expands, now temperature expansion protection body compresses interior flexible annulus and external extension annulus moves to both sides, with the satisfied temperature expansion protection body required space of expanding, can effectively absorb heat and temperature, the temperature of inner conductor is kept compared with stable state, stability in use and high temperature resistant and corrosion resistance are necessarily improved, stability in use is good, applicability is strong, practicality is good.
