Tensile shielded cable

Abstract

The invention provides a tensile shielded cable. The tensile shielded cable is characterized by comprising conductors (1), wherein an insulating layer (2) coats the outside of each conductor (1); an inner shielding layer (3) coats the outside of the insulating layer (2); the inner shielding layer (3) is a copper wire and copper strip composite shielding layer; the copper wire and copper strip composite shielding layer comprises a plurality of soft round copper wires and copper strips coating the outside of the copper wires; an asphalt layer (6) coats the outside of the inner shielding layers (3); a steel wire layer (5) is arranged in the asphalt layer (6); a refractory layer (7) coats the outside of the asphalt layer (6); an outer sheath layer (8) coats the outside of the refractory layer (7); the steel wire layer (5) is surrounded by a plurality of steel wires to form an enclosed roundness; a filler (4) is arranged in a gap between the inner shielding layers (3) and the asphalt layer (6); and the outer sheath layer (8) is made of radiated cross-linking polyolefin or radiated cross-linking ethylene-propylene rubber.

Description

technical field [0001] The invention relates to the technical field of cables and provides a tensile shielded cable. Background technique [0002] With the proposal of the strategy of "accelerating the exploration and development of sea areas and realizing the rapid development of offshore oil and gas", the construction of offshore oil platforms has also entered a golden age. Due to the special requirements of offshore oil platforms for cables, cables for offshore oil platforms are generally imported from the United States, South Korea and other countries. With the improvement of the localization level of offshore oil platforms, domestic requirements for special cables for offshore oil platforms are urgent. It is a new product designed and developed for the environment of oil platforms with super soft and high tensile strength control cables. The cables on oil platforms require softness, tensile strength, oil resistance, high temperature resistance, low temperature resistanc...

Problems solved by technology

Due to the special requirements of offshore oil platforms for cables, cables for offshore oil platforms are generally imported from the United States, South Korea and other countries. With the improvement of the localization level of offshore oil platforms, domestic requirements for special cables for offshore oil platforms are urgent. It is a new product designed and developed for the environment of oil platforms with super soft and high tensile strength control cables. The cables on oil platforms require softness, tensile strength, oil resistance, high temperature resistance, low temperature resistance, friction resistance, etc., which affect the environmental performance of the cables. The requirements are high. In the past, the shielding layer of ordinary cables used on oil platforms was mostly made of metal wire. The cable shielding layer is prone to problems such as bulging of the outer sheath or piercing of the core.
