Background technology
Wires and cables industry is the important supporting industry of the electric power and the two big pillar industries in national economy of communicating by letter; Extremely important status is arranged in national economy; Wherein the industry production total amount accounts for 4 ‰ to 5 ‰ of the total GDP in the whole nation; The important function that the electric wire product plays and carries the energy, transmits information is " blood vessel " and " nerve " of national economy.
The annual submarine cable of China, pipe laying length have several thousand kilometers, and submarine cable accounts for about 10%～15% of whole laying amount.Along with fast development of national economy and island construction, island exploitation continue carry out, the deep-sea energy extraction, domestic demand to submarine cable significantly increases.And common extra large cable only can be used for the 0-100m depth of water, and deep-sea oil exploitation, coastal wind-powered electricity generation all have higher requirement to seabed electric property, water resistance relatively.Current techniques condition, production are equipped under the also relatively backward situation, and domestic also do not have cable enterprise can produce this series products.
At present common 35kV and following submarine cable are as shown in Figure 1; It comprises three power cables and a root communications optical cable; Power cable mainly is made up of water-blocking conductor 1 and the internal shield 2, insulating barrier 3 (XLPE), outer shielding layer 4, water-blocking buffer layer 5, the insulating sleeve 6 that are set in turn in outside the water-blocking conductor 1, is provided with optical cable unit 8 in the gap of power cable, and the space is filled with filler 7 around power cable and the optical cable unit 8; Behind filler 7 roundings; Be provided with twining package tape 9 in its outside, be disposed with metallic shield 10, inner cushion layer 11, armour 12, serving 13 outside the twining package tape 9.
This 35kV reaches with submarine cable and has deficiency:
1, insulation is adopted and is adopted XLPE mostly, and XLPE is to be used for the environment that seawater is more shallow, instructions for use is lower.If be applied to its waterproof of deep-sea and ageing properties relatively poor, influence cable life.
2, do not consider preferably and be electrically connected that metallic shield is adopted insulation phase-splitting sheath outward or metallic shield is being arranged on the twining package tape outside.Adopt insulation phase-splitting sheath, jacket surface out-of-flatness, smooth is when this submarine cable length is longer; Three alternate electric contacts are inhomogeneous; Induced potential can not be offset fully, will make the metal level heating, thereby has influenced the transmitted power of this submarine cable to a great extent.Metallic shield is arranged on outside the twining package tape, three alternate electric field mutual superposition, the damage insulation reduces cable life, and the single factory length of cable is shorter relatively, maintenance (joint) complicated operation.
3, the optical cable unit of this submarine cable is to be arranged in the gap of power cable; And itself and power cable around fill though filler arranged; But can not well fix, this structure optical cable unit does not obtain better protect, when making and laying, fractures easily.
4, there are some ship worms, microbe can corrode extra large cable cable core in the ocean, even metallic shield, insulation.
5, traditional serving all adopts the fiber material of same color, is difficult for identification in the ocean that is laid in, and both has been unfavorable for protection, also is not easy to safeguard.
