Abstract
The utility model discloses a novel environment-friendly, waterproof, anticorrosion, high-strength, high-voltage, and mouse and termite-resisting cable. The cable successively comprises, from inside to outside, a water-resisting copper conductor, a conductor shielding layer, a crosslinked polyethylene insulating layer, an insulating shielding layer, a lead alloy sheath layer, a copper wire shielding layer, a polyvinyl chloride liner layer, a stainless steel wire armored layer, a high-density polyethylene sheath layer, a nylon protection layer, and a polyvinyl chloride protective layer. A copper belt wraps the copper wire shielding layer. Graphite coats the polyvinyl chloride protective layer. The lead alloy sheath layer of the cable is water-resisting and corrosion-resisting. The stainless steel wire armored layer enables tensile strength and intensity of mechanical impact resistance of the cable to be improved. The nylon protection layer enables the cable to be prevented from being bitten by termites and mice. The cable is suitable for large and medium-sized chemical enterprises, sewage treatment plants and seaside areas. The cable can be laid in sewage tanks, neritic regions or the like for underwater operation. Meanwhile, the cable is suitable for areas with many mice or termites and is now the most environment-friendly mouse-resisting method.
Description
Technical field
The utility model relates to a kind of high-tension cable, specifically a kind of novel environment friendly rat-and-ant proof, waterproof anti-corrosion, high-strength high-voltage cable.
Background technology
Existing waterproof, protection against rodents, termite-proof, flame-retarded technology are mainly used in 35KV and following cable, 66KV and above high-tension cable are because of manufacturing process relative complex, raw material, production equipment are had relatively high expectations, therefore need to be explored and research for high-tension cable waterproof, protection against rodents, termite-proof, flame-retarded technology.
CN202394587U discloses a kind of Novel anti-mouse Anti-termite flame-retardant waterproof power cable, below its electric pressure 35KV, adopts waterstop, aluminium-plastic tape to block water, and oversheath has protection against rodents, termite-proof halogen-free and low-smoke flame-retardant polyolefin oversheath.
CN202940054U discloses a kind of waterproof, protection against rodents, Anti-termite power cable, below its electric pressure 35KV, adopt aluminium-plastic tape to add and in water preventing ability, protect waterproof construction, be coated with double-layer spiral galvanized steel strip armour, oversheath adopts waterproof, wear-resisting medium density polyethylene material, can play protection against rodents, the effect such as termite-proof.
All there is the problems such as intensity is low, useful life is short, be easily damaged in existing these high-tension cables.And have more aggressive solvent or ion in land water level higher place, especially water, very easily there is couple corrosion and weak acid caustic corrosion in conventional cable metal sheath, armoring material.
Utility model content
Technical problem to be solved by this invention is to provide a kind of novel environment friendly rat-and-ant proof, waterproof anti-corrosion, high-strength high-voltage cable, and this cable adopts more erosion-resisting material, structural design excellence, and intensity is low, long service life.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of novel environment friendly rat-and-ant proof, waterproof anti-corrosion, high-strength high-voltage cable, be followed successively by from inside to outside the copper conductor that blocks water, conductor shield, crosslinked polyetylene insulated layer, insulation screen, lead alloy sheath, shielding layer of copper wires, polyvinyl chloride inner covering, stainless steel wire armour, high density polyethylene (HDPE) sheath, nylon sheath and polyvinyl chloride overcoat, described shielding layer of copper wires is surrounded with copper strips outward, and described polyvinyl chloride overcoat is coated with graphite outward.
Cable feature of the present invention:
(1) water resistance: conductor blocks water (longitudinally), lead sheath blocks water (radially).
(2) anticorrosion: the material of lead sheath is inertia relatively, can effectively prevent the corrosion in various organic solvents, strong acid and strong base and other common corrosivity places; Nylon sheath wire also has stronger Corrosion Protection simultaneously.
(3) tensile strength: owing to there being stainless steel wire armouring in the construction of cable, make cable there is very high tensile strength and resistance to mechanical shock performance; Be applicable to high-drop installation.
(4) rat-and-ant proof: nylon sheath wire environmental protection is the most reliable Ratproof and termiteproof material.
Adopt lead alloy sheath, can meet block water, corrosion resistant requirement.This structure adopts expressing technique simultaneously, realizes sealing completely, reaches block-water effect; Adopt stainless steel wire as metal armouring layer, effectively improve tensile strength and the anti-mechanical impact strength of cable; Nylon sheath wire, as the rat-and-ant proof structure of environment-friendly type, can effectively stop mouse, the infringement of termite to cable.
The lead alloy sheath of this cable blocks water, corrosion-resistant; Stainless steel wire armouring improves tensile strength and the anti-mechanical impact strength of cable; Termite-proof, anti-mouse gnaws nylon sheath wire.Can be suitable for big-and-middle-sized chemical enterprise, sewage treatment plant and area, seashore.Being suitable for be laid in cesspool, neritic area etc. and moving under water, be applicable to the more area of mouse or termite simultaneously, is the protection against rodents method of at present environmental protection.
This structure applications is in high-tension cable (more than 35KV), corrosion-resistant, improving tension impact strength and nylon sheath wire rat-and-ant proof, the aspect effect such as to gnaw excellent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model cable.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model cable is followed successively by the copper conductor 1 that blocks water, conductor shield 2, crosslinked polyetylene insulated layer 3, insulation screen 4, metal sheath layer 5, shielding layer of copper wires 6, polyvinyl chloride inner covering 7, stainless steel wire armour 8, high density polyethylene (HDPE) restrictive coating 9, nylon sheath 10 and polyvinyl chloride overcoat 11 from inside to outside, the outer copper strips that is surrounded with of described shielding layer of copper wires 6, the outer graphite that is coated with of described polyvinyl chloride overcoat 11.
Metal sheath layer adopt lead alloy sheath block water, can meet block water, corrosion resistant requirement.This structure adopts expressing technique simultaneously, realizes sealing completely, reaches block-water effect; Adopt stainless steel wire as metal armouring layer, effectively improve tensile strength and the anti-mechanical impact strength of cable; Nylon sheath wire, as the rat-and-ant proof structure of environment-friendly type, can effectively stop mouse, the infringement of termite to cable.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection range of the present utility model.
