Abstract
The utility model discloses a special soft power cable. The special soft power cable is characterized by comprising a multi-strand tin-plated copper wire conductor which is formed by stranding a plurality of strands of tin-plated copper wires coaxially by using a wire and cable beam stranding machine, wherein an irradiation ethylene propylene rubber insulating layer extruded by adopting the thin wall of a high-temperature plastic extruder is arranged on the periphery of the multi-strand tin-plated copper wire conductor; a solid filing core which is formed by stranding an insulating wire core and a filling core by using a cable forming machine and extending by adopting extruding equipment is arranged on the periphery of the irradiation ethylene propylene rubber insulating layer; a tin-plated copper wire shielding layer which is woven by using a weaving machine or a soft polyurethane sheath layer which is extruded by the extruding equipment is arranged on the periphery of the solid filling core; and the normal paving and installing temperature is -55 DEG C. The special soft power cable has the advantage of softness, has characteristics of high mechanical strength, high abrasion resistance, aging resistance, cracking resistance, mold resistance, moisture resistance, and acid or alkali erosion resistance as well as the characteristic of softness under a low temperature, and is suitable to be used for power transmission of equipment in special environments such as weapons, electronics, high-end civilian and the like.
Description
Technical field
The utility model is the soft feed cable of a kind of special type; Can adapt to weapons, electronics, high-end narrow space, severe rugged environment work such as civilian; Has the characteristic that mechanical strength height, high abrasion, ageing-resistant, cracking resistance, mould proof, humidity and acid and alkali-resistance corrode; Characteristic has excellent mechanical performance and electrical property.
Background technology
At present; The extraordinary soft feed cable standard of not being correlated with in the cable industry; On with reference to GB/T 12706-2008 " rated voltage 1kV (Um=1.2kV) to 35kV (Um=40.5kV) extruded insulation power cable and annex " standard base, the utility model has increased product correlated performance under particular surroundings: 1. flexibility; 2. low temperature resistant; Performance such as 3. ageing-resistant.Cable is soft, has the characteristic that mechanical strength height, high abrasion, ageing-resistant, cracking resistance, humidity and acid and alkali-resistance corrode, and under cryogenic conditions, has soft characteristic, is applicable to weapons electronics, high-end particular surroundings such as civilian, is used for the electric power of equipment transmission.And formulate according to user's specific (special) requirements, take into full account its applicability and reliability, take into full account low temperature, softness, specific (special) requirements such as wear-resisting, satisfy multiple environment for use requirement, through the sample verification experimental verification designed rationality and reliability.
Summary of the invention
What the utility model proposed is the soft feed cable of a kind of special type, and its purpose is intended to satisfy multiple environment for use requirement, has flexibility, the good extraordinary soft feed cable of performance such as low temperature resistant, ageing-resistant.
The technical solution of the utility model: it is characterized in that the multiply tinned copper wire conductor that the multiply tinned copper wire is twisted together with electric wire bunch of cables winch concentric type; The periphery of multiply tinned copper wire conductor is the ethylene propylene rubber insulated layer of irradiation that adopts high temperature plastic extruding machine thin-walled to extrude; The solid filled core that the periphery of the ethylene propylene rubber insulated layer of irradiation twists together insulated wire cores and filled core and adopt extrusion equipment to extrude with cabler; The periphery of solid filled core is with the tinned copper wire screen of braiding machine braiding or the soft urethane jacket layer of extruding with extrusion equipment; The temperature of normal laying installation is under-55 ℃.
The utlity model has following advantage: 1) working temperature: insulation and sheath material all adopt flexible material, and temperature is used in-55～+ 85 ℃ of scopes for a long time; 2) flexibility: conductor adopts the multiply tinned copper wire, and the filament diameter minimum is merely 0.12mm, adopts the flexible insulation material, has increased the flexibility of cable, reduces to lay the space; 3) stability: conductor material adopts tinned conductor, but resistance to oxidation, and insulation and sheath material can have acid and alkali resistance, oil and other nip using for a long time in the temperature on a large scale; 4) low temperature resistant: cable can solve general material because low temperature lays problems such as being prone to cause sclerosis, embrittlement, thereby satisfy the instructions for use of low temperature environment-55 ℃ of normal laying installations down; 5) three anti-tests: satisfy mould proof among the GJB150, anti-salt fog, anti-damp and hot requirement; 6) wear-resisting: the cable anti-wear performance is good.
