Description
Technical field
The present invention relates to a kind of cable, specifically low, the energy-conserving and environment-protective of a kind of high conduction, cost, water preventing ability are excellent, have three core sea electric power cables of transmission light signal of telecommunication effect when anticorrosion, creep resistant, flexible, transmission power concurrently.。
Background technology
State Grid's cause is advanced by leaps and bounds, and 2009 ~ 2011 years to be not less than 10% speed increment every year.From offshore islands to marshland, rivers and lakes, land, from the offshore oil drilling platform to the coastal occasions such as wind power generation, the demand of various big-lengths seabed, XLPE power cable under water increases severely.Especially still oil and the deep-sea oil of next step Devoting Major Efforts To Developing of China have all been listed the schedule that national development is planned in, and this submarine cable that just need to possess high security transmission of electricity and transmission light electric signal function is finished.Both required that high conduction, cost are low, energy-conserving and environment-protective, water preventing ability are excellent, anticorrosion, creep resistant, antifatigue, require again flexible applicable situation, just must lay simultaneously the compound three core sea electric power cables of the optical fiber that possesses above performance.But existing submarine cable function is all more single.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the deficiency of original sea electric power cable function singleness, provide a kind of optical fiber compound three core sea electric power cables, be applicable to specific (special) requirements, big-length, abominable operational environment, had transmission of electricity and two kinds of functions of the transmission light signal of telecommunication.
The technical solution used in the present invention is as follows:
A kind of optical fiber hybrid submarine power cable; it is characterized in that it comprises the stop water conductor; the outside of stop water conductor is surrounded by conductor shield; the conductor shield outside is surrounded by waterproof tree XLPE insulating barrier successively; insulation screen; the semi-conductive buffer water-blocking band layer; anticorrosion aluminum alloy sheath and PE strengthen protective layer; they form core; many core twisted synthesizing cables; the outside of described many cores is surrounded by modified rubber body packing; also be provided with the Optical Fiber Transmission unit that is positioned at described many core gaps in the modified rubber body packing, the outside of described modified rubber body packing is surrounded by sheath successively; strapping blocks water; wire armoring layer and outer jacket.
The quantity of described core is three.
Institute's outer jacket adds plastics by wire armoring and extrudes and form.
Beneficial effect of the present invention has:
Have that high conduction, cost are low, energy-conserving and environment-protective, integrated water stop, anticorrosion, creep resistant, antifatigue, the advantage such as flexible, the effects such as electric energy transmitting and photosignal are arranged simultaneously, be applicable in rated voltage 26/35kV and the following electric power system.
The present invention has creep resistant, antifatigue, energy-conserving and environment-protective, integrated water stop, and good bending property has high pliability, and has stronger corrosion resistance, anti-electromagnetic interference performance.The transmission light signal of telecommunication effectively, the fine and power transmission and distribution cable of light harvesting has been avoided the secondary wiring, reduce the expenses such as construction and networking, for the operating characteristic of submarine cable, greatly saved manufacturing and installation and maintenance expense, be the intelligentized auxiliary products of electrical network, use face is wider.
The present invention passes through the structural design of the compound three core sea electric power cables of long length fiber and process certification repeatedly, and the performance advantage of contrast similar products at home and abroad, improve process structure and utilized some new synthetic materials, be that product has more that comprehensive waterproof and high conduction, cost are low, energy-conserving and environment-protective, water preventing ability are excellent, anticorrosion, creep resistant, antifatigue, the performance such as flexible: improved the conductor structure design, increased stop water; Having improved insulation uses waterproof tree material to improve cable useful life and fail safe; Increased the integrated water stop performance of aluminum alloy sheath, simultaneously the unit cable core has been had safe protectiveness, cable uses operation safer; Processing technology is simple, need not to increase manufacturing facilities, and has reduced manufacturing cost.
