The utility model discloses mainly improve the rated voltage of new forms of energy electric automobile charging cable, guarantee the compliance of cable simultaneously, select for use nylon to protect in insulating, carry insulation resistance between the high voltage transmission line, reduce the leakage current, increase the area that blocks water simultaneously, prevent the air in steam go into inside the cable greatly, improve new energy automobile charging voltage, shorten new energy automobile charge time, improve the frequency of utilization, reduce to grow when charging and bring not convenient in the use.
Description
Technical field
This utility model relates to electric wire field, is specifically related to a kind of 1500V New-energy electric vehicle charging pile cable.
Background technology
Along with wideling popularize of New-energy electric vehicle, the distinctive electrically-charging equipment demand of New-energy electric vehicle increases, but automobile itself belongs to vehicles of common, the charging of new-energy automobile at present requires time for longer, being typically necessary 6 ~ 12 hours, disposably charge 100 ~ 200 kilometrages, broadly falls into common charging, oversize for the charging interval, directly influence the utilization rate of automobile.For new-energy automobile manufacturer, solve a difficult problem for automobile quick charge, first solve electrically-charging equipment problem, show and suggestion, quick charge, it is necessary to improve charging voltage, improves New-energy electric vehicle charging voltage, improving cable voltage, leakage current is constant, it is necessary to provide the insulation resistance of cable.
In existing cable structure, proof voltage grade is 600V voltage, and temperature resistant grade is 125 DEG C, and structure is: inner wire peripheral hardware cross-linking radiation polyolefin, peripheral hardware sheath.Cross-linking radiation polyolefin in this structure, insulation specific insulation only up to reach 109Ω cm, to need to provide the proof voltage grade of cable itself, it is ensured that the temperature resistant grade of cable and flame retardant rating national standard A level, and do not increase cable complete external diameter, it is ensured that the pull resistance of cable, flexibility, in existing structure, specific insulation needs to reach 1014Ω cm, current all insulation wouldn't meet.
Utility model content
In order to overcome the deficiencies in the prior art, it is provided that a kind of 1500V New-energy electric vehicle charging pile cable, not only increase the insulation resistance between pressure-wire, decrease leakage current, and prevent steam in air from containing inside cable.
For achieving the above object, this utility model provides a kind of 1500V New-energy electric vehicle charging pile cable, including cable core, extrudes waterstop sealing coat outside described cable core, extrudes the outer quilt using 125 DEG C of flame-retardant thermoplastic elastomers at cable outermost layer；Described cable core is drawn tension rope, is centered around Kev and draws four power lines outside tension rope, a ground wire and be symmetricly set on the signal lines of ground wire both sides and constitute by centrally disposed Kev.
Improve further, 125 DEG C of polyolefinic inner insulating layer of flame-proof cross-linking of employing that described power line by copper conductor and is extruded in outside copper conductor successively, use in the insulation of nylon and be configured.
Improving further, described ground wire uses 125 DEG C of polyolefinic inner insulating layer of flame-proof cross-linking by aluminium alloy conductor and being extruded in successively outside aluminium alloy conductor, be configured in the insulation that uses nylon.
Improving further, described signal lines is by detecting signal conductor and being extruded in the insulating barrier of the 125 DEG C of flame-retardant thermoplastic elastomers of employing outside detection signal conductor and constitute.
The beneficial effects of the utility model are:
1. this utility model mainly improves the rated voltage of New-energy electric vehicle charging cable, ensure the flexibility of cable simultaneously, protect in selecting nylon insulation, improve the insulation resistance between pressure-wire, reduce leakage current, increase waterstop simultaneously, prevent steam in air from containing inside cable；New-energy automobile charging voltage is improved, shortens the new-energy automobile charging interval, improve and use frequency, reduce because of charging duration bring in use the most convenient.
2. on the basis of existing, New-energy electric vehicle charging cable, it is charged as DC current, but charging gun cable is hand-held, improve voltage, for the leakage current that holding is less, require higher relative to the insulating properties of cable, using on material, simple use nylon, cable the most fire-retardant, and cable is the hardest, and use flame-retardant crosslinking polyethylene and nylon co-extrusion mode extrusion, flame retardant effect can be reached, the leakage current (because increasing relative volume resistivity) of insulation can be reduced again；
3. this cable, detects voltage AC.10KV, and power line insulation resistance can reach 10M Ω/KM；
4. 13.30 squares of power line cross section, holding wire sectional area 0.75 square, use 1500V direct current 100A, environment is for sealing in 3% saline water-bath, and water temperature 20 DEG C, experimental situation temperature 20 DEG C, charging duration 24 hours, water temperature is without raising.
