Description
Technical field
The present invention relates to a kind of cable, particularly relate to a kind of novel bank electric system cable.
Background technology
Do not use marine generator group during so-called bank electric system refers to ship berthing and powered by shore electric power.Harbour bank electricity by boats and ships disembarkation electrical connection cable and shore connection box to the power electrical apparatus on boats and ships, guarantee the need for electricity meeting marine electric installation.If use diesel-electric set electric supply during naval vessel alongside, diesel oil produces a large amount of sulfide and nitrogen oxide in combustion, pollutes surrounding enviroment.International Maritime Organization (IMO) data show: NOx and SOx is main pollutant, and the whole world is that the boats and ships of power are every year to airborne release 1,000 ten thousand tons of NOx, 8,500,000 tons of Sox with diesel oil; Pollutant can be transmitted to the area beyond 1000km by weather effect.If stop diesel engine generator generating, change by harbour bank electricity mains supply, be equivalent to the flue gas reducing discharging equal-wattage diesel engine unit, simultaneously because naval vessel uses berth unit or the generating of main diesel generating set of configuration, efficiency is lower, cost of electricity-generating is higher, traditional diesel generator group is replaced to power with harbour mains supply, energy-saving effect is remarkable, moreover diesel generating set generating on naval vessel, vibration & noise is comparatively large, must cause noise pollution, after using harbour bank electricity, also can eliminate above-mentioned impact, improve the life comfortableness of warship person.Bank electric system be conducive to energy-conservation, reduce discharging, noise reduction meets the trend of Green Development, environmental protection aspect is significant.Boats and ships utilize bank electricity problem to be that Department of Transportation intends in " 12 " period powerful energy-saving and emission-reduction new measure advanced, therefore naval vessel is when landing pier, generally all need to connect with shore electric power, but along with the large scale development on naval vessel, existing naval vessel harbour bank electric system can not meet user demand completely, need our designed in advance a new generation harbour bank electric system, wherein cable mostly is CEFR/SA type, namely ethylene propylene rubber insulated, chloroprene rubber sheath, bunchy flame retardant type flexible electric power cable peculiar to vessel, also the Heavy Weight existed, bendability is poor, the problems such as not wear-resisting, overcome the deficiency of existing shore connection cable, carry out Improvement design, manufacturing novel shore connection cable is also the task of top priority.
Summary of the invention
The object of the invention is to adapt to harbour bank electric system of new generation, overcome the problems such as Heavy Weight, bendability that existing bank electrical connection cable mainly exists be poor, not wear-resisting, and improve its dynamic anti-towing and static croop property, take into account the requirement in useful life under light weight and complex environment, be a kind of novel bank electric system cable simultaneously.
Technical scheme of the present invention is: described cable comprises conductor, isolation strip, insulating barrier, center bedding core, integration inner cushion layer, nonmetal reinforcement fibrous layers and oversheath, separator and insulating barrier formation insulated wire cores is set gradually outside described conductor, the many mutual stranded formation cable cores of insulated wire cores, described center bedding core is arranged on cable core center, many described insulated wire cores deciles are arranged on outside the bedding core of center, described integrated inner cushion layer is extruded in every root insulated wire cores surface and adjacent slits thereof, nonmetal reinforcement fibrous layers and oversheath is set gradually outside described integrated inner cushion layer.
Described conductor is the 5th or the 6th class conductor of GB/T3956 regulation, and roundness reaches 98%.
The semiconductive nylon strap of to be thickness be in described isolation strip 0.12mm, spiral wrapped at conductive surface, rate of putting up is not little by 45%.
Described insulating barrier is ethylene propylene diene rubber insulating barrier.
Described center bedding core is semi-cure rubber adhesive tape.
Described integrated inner cushion layer is low-intensity Halogen sizing material layer.
Described nonmetal reinforcement fibrous layers is braiding or stranded aramid fiber layer.
Described oversheath is Polyether-type thermoplastic polyurethane elastomer (TPU) sheath.
Compact conformation of the present invention, weight are light, good, the anti-towing of resist bending, pliability, environment-protecting asepsis, fire resistance are good.
Advantage of the present invention is:
1, isolation strip adopts semiconductive nylon strap, not only can ensure the rear roundness of the 5th or the 6th class conductor minute-pressure setting, separator is formed between conductor and insulating barrier, prevent insulating barrier embed Insulating gap and be difficult to peel off and bending time microcosmic displacement difficulty, the microcosmic simultaneously can eliminating conductive surface existence is bad, improves the reliability of insulation under Static and dynamic further;
2, integration inner cushion layer employing low-intensity Halogen filler extrudes mode with pressure to carry out, it is made to fill up surface gap and coated whole cable core, play conventional stranding filler, whole effects of band and inner cushion layer, not only rise to tie up and fixedly make its Stability Analysis of Structures, the effect of outward appearance rounding, also implement inner cushion layer in the lump, for follow-up nonmetal reinforcement fibrous layers provides buffering and isolation, low intensive characteristic does not affect the flexible of cable yet, main is that low-intensity Halogen filler can absorb heat at a certain temperature, discharge a large amount of crystallizations water, reduce cable temperature, stop insulating barrier melting degraded, greatly can improve the comprehensive oxygen index of whole cable, fire retardancy improves greatly,
3, nonmetal reinforcement fibrous layers has superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, lightweight, its intensity is 5-6 times of steel wire, modulus is 2-3 times of steel wire or glass fibre, toughness is 2 times of steel wire, and weight is only about 1/5 of steel wire, the temperature of 560 degree, do not decompose, do not melt, there is good insulating properties and ageing resistace, there is very long life cycle, adopt it as stiffener, on weight increase and bending property all without any impact, it also avoid the magnetic hysteresis loss that magnetic materials such as adopting steel wire brings to cable, dynamic anti-towing and static croop property can be ensured,
4, the requirement completely environmentally protected of whole construction of cable element, selects the halogens such as not chloride, bromine, not leaded, the insulation of the heavy metal such as chromium, mercury, integrated inner cushion layer and sheath material.Cable can not discharge the gas and the dense smoke that human body respiration organ are had to intense stimulus when flame condition., smoke toxicity index ≯ 5, smoke density is by minimum light transmittance≤80%, and TPUE (TPU) protective cover material is very suitable for shore connection cable, can obtain a large amount of uses.
