Abstract
The utility model provides an environmental-protective fire-proof nanometer high-voltage cable, comprising from interior to exterior three single cables, an inorganic mineral substance filling layer, a glass bale of cloth belt, a flame resistant inner covering, a steel belt and a flame resistant sheath one after another. The single cable comprises from interior to exterior a conductor, an inner semi-conductive layer, a fire-proof nanometer insulation layer, an insulation layer, an outer semi-conductive layer, a protective layer and a copper belt one after another. The utility model alters the structure of traditional high-voltage cable and has the advantages of low smoke, no toxicity, no halogen, flame resistance, ageing resistance, internal heat resistance, open flame resistance and environment protection. The environmental-protective fire-proof nanometer high-voltage cable is a new product instead of the traditional products.
Description
Technical field
The utility model relates to a kind of fire prevention high-tension cable, belongs to technical field of electric wires and cables.
Background technology
Existing high-tension bus-bar cable is to adopt common DIN standard production to make, and its structure is: coat heat-resisting 90 ℃ interior semiconductive layer, outer semiconductive layer, burnt connection polyethylene, polyvinyl chloride insulation layer outside copper conductor.Find in the practice that this high-tension bus-bar cable is all thermo-labile, and is not fire-resistant, more can not prevent fires; The conductor overload current is easy to puncture insulating barrier, causes short circuit, initiation fire; In naked light, the insulating barrier that can ignite very soon causes the electricity fire combustion-supporting, enlarges the condition of a disaster.If the generation the condition of a disaster will cause heavy losses to national economy as the large-area power-cuts of the U.S. in 2003 and Britain.
Summary of the invention
The purpose of this utility model is that to overcome above-mentioned technology not enough and the nano environmental protection fire prevention high-tension cable of a kind of both Nai Neire, anti-naked light and environmental protection is provided, and its production cost is low, and processing technology is simple.
For achieving the above object, the utility model provides following technical scheme: design a kind of nano environmental protection fire prevention high-tension cable, it comprises from inside to outside successively: 3 unit cables, inorganic mineral packed layer, glass cloth band, fire-retardant inner covering, steel band and fire retardant jackets; Described unit cable comprises from inside to outside successively: conductor, interior semiconductive layer, nanometer fireproof insulating barrier, insulating barrier, outer semiconductive layer, protective layer and copper strips.
In the such scheme, described interior semiconductive layer is extruded and is coated on the described conductor, one-shot forming.
In the such scheme, described nanometer fireproof insulating barrier is extruded and is coated on the described interior semiconductive layer, one-shot forming.
In the such scheme, described outer semiconductive layer is extruded and is coated on the described insulating barrier, one-shot forming.
Nano environmental protection fire prevention high-tension cable of the present utility model, owing to increased the nanometer fireproof insulating barrier, and interior semiconductive layer and outer semiconductive layer adopt nano environmental protection partly to lead insulating material, and make original insulating barrier into low smoke and zero halogen, difficult combustion nonflame material, fundamentally changed the internal structure of high-tension bus-bar cable, can be from the generation of control circuit fire on the source.Its characteristic is: working temperature is increased to 340 ℃ by 90 ℃; 1 times of current overload, conductor temperature-40 are ℃ to 340 ℃ of sustainable power supplies 1.5 hours, and not short circuit does not cause the electricity fire.Under the ablation of 800-1200 ℃ of naked light, electric wire can not ignite in 1.5 hours that electricity fights can continued power.In the naked light ablation process, the not only difficult combustion nonflame of insulating barrier, and no longer discharge suffocative toxic gas; Nanometer fireproof insulating barrier does not wherein not only fire, and can at high temperature play insulating effect, and can guarantee indeformablely in 1200 ℃, meets GB and IEC relevant criterion fully.This high-tension cable has low cigarette, nontoxic, Halogen, fire-retardant, aging-resistant characteristic, and is grease proofing, anticorrosion, and antiacid alkali is more than three times of traditional electric wire useful life.Main performance is: rated voltage≤110KV, and the long-term work temperature :-40 to 120 ℃, the maximum operating temperature of (1 hour) cable in short-term :≤340 ℃.

In the such scheme, interior semiconductive layer 11 is extruded and is coated on the conductor 12, one-shot forming.
In the such scheme, nanometer fireproof insulating barrier 9 is extruded and is coated on the interior semiconductive layer 11, one-shot forming.
In the such scheme, outer semiconductive layer 6 is extruded and is coated on the insulating barrier 7, one-shot forming.
Described nanometer fireproof insulating barrier 9 employing nano environmental protection fire prevention mineral insulating materials, prescription and performance see our company's application for a patent for invention for details, and (application number: 200410000018.8), maximum operating temperature can reach 1200 ℃.
Can on the basis of conventional production equipment, mould and region of interest be undergone technological transformation, just can produce this product in batches, do not need to increase equipment frock and operation, be easy to popularize and produce and promote.
The utility model has changed the structure of conventional high-tension cable, has adopted new material, and Nai Neire, anti-naked light are anticorrosion weather-proof, has the characteristic of safety, fire prevention, anti-overload, long service life, is the renewal product of similar traditional product.
