Abstract
The utility model discloses a silicon rubber insulating power cable which comprises a plurality of strands of conductors. Ceramic fireproof silicon rubber insulating layers are extruded outside the conductors; a plurality of conductors extruded with the insulating layers are stranded into a cable core; a polyvinyl chloride inner sheath is wrapped outside the cable core; glass cords are filled between the cable core and the inner sheath; an armor layer is coated outside the inner sheath; and an outer sheath is coated outside the armor layer. According to the utility model, ceramic fireproof silicon rubber is used as the insulating layers and can be formed into ceramic solids after being burnt at high temperature or by flame, has a certain mechanical strength and excellent electric insulativity and can well take an effect of protecting the normal operation of a circuit; and the glass cords with excellent fireproof performance are used as fireproof filling materials, so that the fireproof performance of the cable is effectively improved. The silicon rubber insulating power cable is suitable for densely inhabited districts such as high-rise buildings, superstores and the like.
Description
Technical field
The utility model relates to a kind of power cable, is specially a kind of resistant to elevated temperatures silicon rubber insulation power cable.
Background technology
Fire-resisting cable is widely used in important department and public places such as skyscraper, subway, power plant, nuclear power station; Fire-resisting cable in the market, and what adopt is magnesia mineral insulation fire-resisting cable and mica tape is wrapped, plastics are compound insulated fireproof cable; The former manufacturing cost is high, and it is big to lay difficulty; The latter has certain unsteadiness, and a lot of mica tapes are thicker, hardness is big, and binder content is high, and mica sheet comes off easily in wrapped process, and the spy is the manufacturing of small bore fire-resisting cable fully, and the quality of product is difficult to guarantee.
The utility model content
The purpose of the utility model provides a kind of silicon rubber insulation power cable, to have the problem that fire resistance power cable cost height and fire resistance can not satisfy instructions for use in the solution prior art.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of silicon rubber insulation power cable; It is characterized in that: include the multiply conductor, said conductor is extruded with potteryization fire-resistant silicon rubber insulating barrier outward, and the conductor that said multiply is extruded with insulating barrier is twisted into cable core; Said cable core is surrounded with the polyvinyl chloride inner sheath outward; Be filled with glass cord between said cable core and the inner sheath, said inner sheath is coated with armour, and said armour is coated with oversheath.
Described a kind of silicon rubber insulation power cable is characterized in that: said armour is a LWA light wire armoured.
Described a kind of silicon rubber insulation power cable, it is characterized in that: said oversheath is processed by polythene material.
The beneficial effect of the utility model is:
The utility model adopts potteryization fire-resistant silicon rubber as insulating barrier, after burning through high temperature or flame, can form potteryization solid, has certain mechanical strength and excellent electric insulating ability, can play the effect that protection circuit normally moves preferably; Adopt the good glass cord of fire resistance as fire-resistant packing material, effectively improved the fire resistance of cable.The utility model is applicable to densely inhabited districts such as skyscraper, megastore.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model includes multiply conductor 1, is extruded with potteryization fire-resistant silicon rubber insulating barrier 2 outside the conductor 1, and the conductor 1 that multiply is extruded with insulating barrier 2 is twisted into cable core; Cable core is surrounded with polyvinyl chloride inner sheath 4 outward; Be filled with glass cord 3 between said cable core and the inner sheath 4, inner sheath 4 is coated with armour 5, and armour 5 is coated with oversheath 6.
Armour 5 LWA light wire armoureds.Oversheath 6 is processed by polythene material.
