Abstract
An EP type cross-linked PE insulating and frame-retardant control cable comprises simple insulating cable core or multiple insulating cable cores twisted together, frame-retardant filling materials are filled in the gap between the cable cores and frame-retardant belts are used to wind the cable cores for fixation. A frame-retardant jacket is arranged at outermost surface of the cable cores. Because the PE insulating cable in the utility model widely adapts halogen-free frame-retardant material, the cable has excellent frame-retardant performance. The cable can effectively prevent the smoke and poisonous harmful gas generating in the fire hazard of electric control wires. The cable also has high safety reliability and long service life. The utility model is suitable for power and signal control wires in the places with population density and requirement for safety reliability of equipment such as stations, hospitals, subways, houses and office buildings.
Description
Technical field
The utility model relates to a kind of power transmission cable, particularly relates to the crosslinked polyetylene insulated fire-retardant control cable of a kind of environment-friendly type.
Prior art
The low smoke and zero halogen control cable mainly is applicable to electrical control and the monitoring loop higher to safety requirements.The control loop suitable as occasions such as hotel, hospital, subway, aircraft, car and boat.Smoke density is little during this product burning, the light transmittance height, and no halogen acid gas is emitted, and no harmful side product belongs to environmentally friendly machine.
According to statistics, the fire incident that causes because of reasons such as aging circuit, electric faults causes the example of casualties to show in a large number, most casualties are not directly burnt by fire or burn to death, but because the poisonous dense smoke of a large amount of Halogens that fire produces is lost survivor's sight line, and to generation strong impulse effects such as eye, mouth, noses, influence respiratory system, disturb the brain nervous centralis, the survivor can not be saved oneself and injures and deaths.Simultaneously, a large amount of toxic and harmfuls also bring very big difficulty to rescue work.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of crosslinked polyetylene insulated control cable of environment-friendly type that can overcome the defective of prior art, it adopts the insulating material of crosslinked polyethylene as cable, other all adopts bittern-free flame-proof material such as cable core packing material, cable core band and oversheath etc., can improve the fire resistance of cable greatly, and the smokescope and the pernicious gas that reduce when burning are overflowed the security reliability of raising cable.
For achieving the above object, the technical solution of the utility model is: the crosslinked polyetylene insulated fire-retardant control cable of described environment-friendly type is made up of single insulated wire cores, or form by several insulated wire cores are stranded, gap between each insulated wire cores is filled with the anti-flammability filler, and then wrapped anti-flammability band fixed, and outermost layer then wraps up the anti-flammability oversheath.
Polyethylene-insulated power cable of the present utility model is owing to extensively adopted bittern-free flame-proof material, therefore has excellent flame-retardant, and smog that has produced because of burning when effectively having checked the electric control circuit fire incident and toxic and harmful are overflowed, improve the security reliability and the useful life of cable, be especially suitable for use as the power supply densely populated and that the higher place of device security reliability requirement such as station, hospital, subway, dwelling house and office building etc. are located and the control circuit of signal.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the present utility model;
Fig. 2 is the structural representation of second embodiment of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
See also Fig. 1: be a specific embodiment of the present utility model.The crosslinked polyetylene insulated fire-retardant control cable of this environment-friendly type is by seven insulated wire cores, 1 stranded forming, gap between each insulated wire cores 1 is filled with anti-flammability filler 2, and then wrapped anti-flammability band 3 fixed, and outermost layer then wraps up anti-flammability oversheath 6.
Described insulated wire cores 1 comprises conductor 11 and is wrapped in the insulating barrier 12 of these conductor 11 peripheries.The insulating material of described insulating barrier 12 is a crosslinked polyethylene, adopts the two step method production after improving.This crosslinked polyethylene belongs to the Halogen material, and its electric insulating quality and mechanical performance all are better than polyethylene and the polyvinyl chloride used always, and has improved the long-term work temperature of cable, and the working temperature grade of crosslinked polyethylene is 90 ℃.And polyethylene and polyvinyl chloride are 70 ℃.
Described anti-flammability filler 2 adopts high flame retardant fire prevention asbestos cord, and this material does not prolong combustion, and its temperature resistant grade reaches more than 450 ℃.
Described anti-flammability band 3 is the low-smoke non-halogen flame-retardant band, and is wrapped two-layer altogether.The performance of anti-flammability band 3 must satisfy the requirement of category-A fire retardancy test.Even ignition of cable burning, this anti-flammability band 3 can form a closely knit isolated protective layer, stops flame and oxygen to enter in the cable core, the cable core 1 of can effectively avoiding insulating fire burns.
Described oversheath 6 adopts low-smoke halogen-free flame-retardant sheath material.This material is not only fire-retardant, and when burning smokescope low, no pernicious gas is emitted, and the respiratory system of human body is had no stimulation, and can not constitute a serious threat to the life security of humans and animals.
Described conductor 11 can adopt 1 class rigid structure, 2 class lay configuration or 5 class soft junction structure conductors, and its every performance index all meet the GB/T3956-1977 standard.
As shown in Figure 2, be the embodiment of another multicore cable of the present utility model.For gnawing, the fire resistance that further strengthens control cable and anti-mouse bite, improve its safe and reliable property, on the basis of above-mentioned first embodiment, the utility model can also be set up inner covering 4 and armour 5, and they are wrapped successively between described anti-flammability band 3 and anti-flammability oversheath 6.Described inner covering 4 is the low smoke and zero halogen inner covering, and described armour 5 is the steel-tape armouring layer.
