Description

Copper core conductor aluminosilicate refractory fiber insulation wrought superalloy sheath fire-resisting cable

Technical field:

The utility model relates to the power transmission and transforming equipment field, is a kind of copper core conductor aluminosilicate refractory fiber insulation wrought superalloy sheath superhigh temperature fire-resisting cable specifically.

Background technology:

In the special cable kind, fire-resisting cable and superhigh temperature cable have been an important trend, though the high-temperature cable electric energy loss is big slightly, occasion at some higher temperatures, then very easily damage with common cable, high-temperature cable can safe operation, is indispensable kind in modern industry and the military project.

The development technical merit of China's high-temperature cable can not satisfy the new markets demand far away at present, China's technology in this respect far lags behind external advanced country, closely the high-temperature cable of half needs from external import, and domestic some factory focuses mostly in some little factories, technology development and production capacity a little less than, particularly production and processing still is confined to cable existing equipment and frock, and the exploitation of material also fails to break through the circle of existing cable material; Therefore need provide a kind of novel fire resistant cable.

Summary of the invention:

For solving the problem that prior art exists, the utility model spy provides a kind of copper core conductor aluminosilicate refractory fiber insulation wrought superalloy sheath superhigh temperature fire-resisting cable, is mainly used in Aero-Space, military project, heating furnace, chemical reaction kettle, the nuclear island of nuclear power station and industry such as iron and steel.Have high temperature resistant, fire prevention, explosion-proof, waterproof, radiation hardness, corrosion resistance is strong, mechanical strength is high, have long, characteristics such as ampacity is big, overload capacity is strong of good ground connection performance, life-span.This product has changed the material type selecting of conventional high-temperature and fire-resisting cable, the casting mica material that flame retardant coating is selected, with synthetic fluorophologopite powder is primary raw material, annotate and form through fusing, burning, have characteristics such as electric insulation, high temperature resistant, corrosion-resistant, anti-oxidant, creep resistant, flexible, machinable, overcome common mica material non-refractory, low, the easy pulverizing of compression strength, easily divided stripping and disposable drawback, this material is using below 1100 ℃, and is indeformable, not softening.The aluminosilicate refractory fiber insulating material is a raw material with the refractory fibre, adds an amount of bond, forms through mechanism.Material has high-strength tear resistance, and high-flexibility can be in the medium-term and long-term work of 1200 ℃ environment.Sheath is selected the wrought superalloy material for use, and operating temperature range-253～1320 ℃ has good mechanical performance and comprehensive strong, toughness index, has higher anti-oxidant, corrosion resistance.

The technical solution adopted in the utility model is:

Copper core conductor aluminosilicate refractory fiber insulation wrought superalloy sheath fire-resisting cable, comprise conductor: have plurality of conductors, every conductor all is enclosed with the fusion-cast synthetic mica layer outward, each fusion-cast synthetic mica layer all is enclosed with the aluminosilicate refractory fiber insulating material outward, described conductor, fusion-cast synthetic mica layer, aluminosilicate refractory fiber insulating material constitute stub, it is wrapped that some stubs are wrapped with aluminosilicate refractory fiber, the wrapped wrought superalloy sheath that is wrapped with of aluminosilicate refractory fiber.

Described copper core conductor aluminosilicate refractory fiber insulation wrought superalloy sheath fire-resisting cable: described conductor is some copper thin wire coileds, and described casting mica material is to be primary raw material with synthetic fluorophologopite powder, through fusing, burn to annotate and form; Described aluminosilicate refractory fiber insulating material is to be raw material with the refractory fibre, adds an amount of bond, processes through plant equipment; Described wrought superalloy sheath is the cylinder that adopts the wrought superalloy material to make.

Advantage of the present utility model is:

The utlity model has high temperature resistant, fire prevention, explosion-proof, waterproof, radiation hardness, corrosion resistance is strong, mechanical strength is high, have long, characteristics such as ampacity is big, overload capacity is strong of good ground connection performance, life-span; And overcome the condition that traditional fireproof high-temperature resistant cable can only use in 800 ℃ and following lower environment, the product heatproof reaches 1100 ℃, heat resistance than traditional common high temperature-resistant cable has improved several times, the material that is adopted all can normally move in 1100 ℃ environment, the resistance to elevated temperatures that not only has superelevation has fire-resistance property preferably simultaneously.The high anti-oxidation temperature of wrought superalloy sheath reaches 1320 ℃, satisfied the specific (special) requirements that cable uses in the harsh environment of high temperature, the useful life of having improved such cable.
