Problems solved by technology

[0003] In order to meet the needs of informatization, shore power cables containing optical fibers have appeared one after another. However, the existing technology simply places optical fibers in the cables, and does not provide a solution to the reliability of optical fibers. When the cables are stretched and bent many times In the process of using, the optical fiber is prone to breakage, the transmission performance of the optical fiber cannot be guaranteed, and the shore power cable is often corroded by salt and alkali, which often leads to a decrease in mechanical properties and affects the use

Embodiment 1

[0046]An optical fiber composite shore power cable, consisting of an outer sheath layer, a strengthening layer, 3 power line units, 1 ground line unit, 4 signal line units and 1 optical fiber unit;

[0047] Among them, the 3 power line units and 1 ground line unit adopt a short-pitch stranded structure, the stranding pitch ratio is 10, the optical fiber unit is located in the center of the power line unit and the ground line unit, and the signal line unit is located outside, the twisting is completed Finally, nylon fiber rope is used to weave to form a reinforcement layer, which is located inside the outer sheath layer, and the two together cover the power line unit, ground line unit, signal line unit, and optical fiber unit.

[0048] The outer sheath layer is composed of the following components in parts by weight:

[0049] 70 parts of fluororubber, 20 parts of carboxyl-terminated liquid fluororubber, 25 parts of chlorosulfonated polyethylene rubber, 10 parts of ethylene-viny...

Embodiment 2

[0061] Basically the same as Example 1, the difference is that the outer sheath layer is made up of the following parts by weight:

[0062] 80 parts of fluororubber, 25 parts of carboxyl-terminated liquid fluororubber, 20 parts of chlorosulfonated polyethylene rubber, 10 parts of ethylene-vinyl acetate copolymer, 10 parts of magnesium aluminum hydrotalcite, 5 parts of magnesium hydroxide, 6 parts of aluminum hydroxide, 3 parts of carbon fiber, 1 part of microcrystalline paraffin, 0.12 part of zinc stearate, 0.2 part of glycidyl methacrylate, 0.2 part of crosslinking agent DCP, 0.1 part of crosslinking agent TAIC, 0.1 part of auxiliary crosslinking agent OV-POSS.

[0063] After testing, the tensile strength is 21.1MPa, the elongation at break is 425%, the oxygen index is 31%, the water absorption rate is ≤0.1% at room temperature for 24 hours, thermal shock test (150±2°C): no cracking, low temperature impact test (-40±2 °C): no cracking.

Abstract

The invention relates to the technical field of power cables, in particular to an optical fiber composite shore power cable which is composed of an outer sheath layer, a reinforcing layer, a plurality of power line units, a ground wire unit, a plurality of signal line units and an optical fiber unit. The reinforcing layer is located at the inner side of the outer sheath layer, the power line units, the ground wire unit, the signal line units and the optical fiber unit are jointly coated with the reinforcing layer and the outer sheath layer, and through testing, the prepared optical fiber composite shore power cable manufactured of the present invention is subjected to dynamic bending testing under the bending radius of four times of the outer diameter of the cable, and the core of the bare optical fiber is not broken when the number of times of bending exceeds 50,000.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an optical fiber composite shore power cable. Background technique [0002] After the ship docks, there are still people on board. In the past, fuel-fired power generation was used to ensure the daily needs of these people. However, fuel-fired power generation will bring air pollution, so a cable connecting the ship and the dock power supply box is widely used. , This kind of cable is collectively called shore power cable. Shore power cables provide clean electric energy for people to continue working and living on board when the ship is docked, which significantly reduces the cost of use and avoids environmental pollution problems. Usually, the shore power cable is wound on the reel. After the ship docks, the cable is pulled out from the reel and connected to the power supply box on the shore of the wharf. Therefore, the cable needs to be resistant to wear, bending and ten...
