Abstract
The utility model relates to the improvement of an electric power transmission cable, in particular relates to a high temperature resistant cable for high working temperature of conductor, which is characterized in that: a cable insulation layer is formed by high temperature resistant fluoroplastic and silicone rubber, an outer sheath is formed by PVC, and a glass fiber woven layer is provided between the insulation layer and the outer sheath. Due to the thermal insulation and fire retardant of the glass fiber outside the insulation layer, and the PVC with low cost and high anti-wearing performance as the outer sheath, thus the high temperature resistant cable can not only have the high temperature resistance and be suitable for long term working under 200 to 250 Celsius system, but also the thin PVC sheath can facilitate the cable with high anti-wearing performance and protect the insulation layer against damages when in construction; moreover, the cable is simple to manufacture and produce with low cost, , the cost can be reduced about 30per cent compared with that of fluoroplastic, silicone rubber insulation and sheath cable. The PVC sheath material can also adopt the other improved materials to meet with the using requirements such as protection against rat and ant, and resistance to acid and alkali, etc.
Description
Technical field
Utility model is about the improvement to the electric power handling cable, relates in particular to the higher high temperature-resistant cable of a kind of conductor working temperature.
Background technology
The cable that uses as power plant, steel mill etc. in some hot environments not only needs to bear ambient temperature higher as 90-105 ℃, and especially need bear higher core conductor temperatures as about 200 ℃.Common polyvinyl chloride (PVC) insulation and jacketed cable, because of the PVC non-refractory, thereby the above-mentioned instructions for use of incompatibility; Fluoroplastics, silicon rubber insulation and jacketed cable, its heat resistance meets the demands, but the oversheath resistance to wear is relatively poor, very easily wear and tear when cable is laid, and then influence insulation property, and cost is higher relatively; Directly adopt fluoroplastics, silicon rubber to make insulating barrier, the PVC sheath that the external application resistance to wear is good, then poor because of the PVC heat-resisting quantity, need to strengthen fluoroplastics, silicon rubber insulation layer thickness, to reduce the outer temperature of insulating barrier, so not only cause cable cost to rise, and cable size is with overstriking.Therefore people can only adopt the fire-resisting cable of flame retardant type to replace usually, and as disclosed high temperature-resistant cables such as Chinese patents 92223066,94221521,00216500, insulation, centre are surrounded by fire prevention mica layer, outer jacket structure in all adopting.Yet fire-resisting cable uses as the heatproof cable, and is higher because of the flame retardant coating cost, and strengthened use cost.Chinese patent 93225361 disclosed a kind of glass fibre high temperature-resistant cables; its structure is insulation film or the laminated film that holds different temperature resistant grades outside lead; the outsourcing alkali-free glass fibre weaves protective layer and coated and the good resin of film compatibility again, through around knot insulating barrier and protective layer being combined closely.Yet this cable is not only made complexity, needs skin glass fiber and interior insulation film around striking up partnership, and directly adopts glass fibre to make oversheath, because glass fibre is not wear-resisting, very easily fray impairedly in the construction, cause fibrous fracture, and then will influence primary insulation.Also have and coat pitch on glass fibre, with the resistance to wear of increase glass fibre, but pitch is not only inflammable, and the resistance to elevated temperatures extreme difference.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of production cost low, manufactures simply, does not increase the cable footpath again, and the sheath resistance to wear is good, the high temperature-resistant cable of being convenient to lay.
The utility model purpose realizes, the main improvement is to set up glass fibre to make intermediate thermal insulating layer between insulating barrier and sheath, with effective reduction exospheric temperature, make it to be suitable for PVC cheap and that resistance to wear is good and make oversheath, thereby satisfy the especially instructions for use of the high temperature of anti-core of cable heatproof.Specifically, the utility model high temperature-resistant cable comprises conductor wire core, insulating barrier and oversheath, it is characterized in that said insulating barrier is made of resistant to elevated temperatures fluoroplastics or silicon rubber, and oversheath is made of PVC, between said insulating barrier and oversheath glass layer is arranged.
For reducing cable cost, according to the serviceability temperature requirement, said fluoroplastics of utility model or silicon rubber inner insulating layer thickness are comparatively suitable with 0.3-1.0mm.Said glass layer can be the glass fiber braid, also can be the glass fiber winding layer, and its effect mainly is heat insulation, to reduce insulating barrier periphery temperature, secondly also plays humidification, has certain anti-fire action simultaneously concurrently.
Utility model increases heat insulation, the fireprotection layer of glass fibre, thereby does not increase thickness of insulating layer owing to adopt outside interior resistant to elevated temperatures fluoroplastics or silicone rubber insulation layer, just can directly adopt the cheap good PVC of resistance to wear to make oversheath.The high temperature-resistant cable that constitutes of structure thus, not only resistance to elevated temperatures is good, and cable can be 200-250 ℃ of normal long-term work down, and thin PVC sheath makes cable have better resistance to wear again, can play the effect of protection insulating barrier when construction; And cables manufacturing production is simple, and cheap, cost can reduce about 30% than fluoroplastics, silicon rubber insulation and jacketed cable.Utility model PVC sheath material can also adopt other various material modified, satisfies such as protection against rodents, anti-ant, acid-fast alkali-proof instructions for use.
Below in conjunction with two indefiniteness embodiment, further specify utility model.
