Problems solved by technology

[0003] In the prior art, the sheath layer is almost used in order to reduce the weight of the cable. However, bending and pulling for a long time will easily lead to the breakage of the sheath layer, resulting in moisture erosion and penetration, which seriously affects the service life of the cable.

The thin-wall lightweight meter cable comprises a cable core and a sheath layer coating the outer side of the cablecore, wherein the sheath layer is prepared from the raw materials in parts by weight: 60-80 parts of ethylene propylene terpolymer rubber, 40-50 parts of polyurethane rubber, 50-60 parts of nitrile silicone rubber, 6-10 parts of vulcanizer, 40-50 parts of vermiculite powder, 20-30 parts of precipitated barium sulfate, 60-70 parts of channel carbon black, 4-8 parts of octyl phenolic aldehyde tackifying resin, 40-50 parts of carbon fibers, 4-8 parts of propylene glycol polysebacate, 2-4 parts of modified soybean oil and 3-5 parts of anti-aging agent.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a thin-walled lightweight instrument cable for oil and gas engineering. Background technique [0002] With the exploitation of offshore oil and gas energy, there are more and more thin-walled lightweight instrument cables used in oil and gas engineering, and the performance requirements are getting higher and higher, especially the sheath layer, which is the main component of the cable weight, needs to be minimized. It has the requirements of adapting to the multi-moisture erosion and penetration of the oil and gas engineering environment and the cable can run safely for about 25 years. [0003] In the prior art, the sheath layer is almost used in order to reduce the weight of the cable. However, bending and pulling for a long time will easily lead to the breakage of the sheath layer, resulting in moisture erosion and penetration, which seriously affects the service life of the ca...
