Embodiment 1
[0023] like figure 1 As shown, the high-temperature-resistant soft overall shielding instrument cable for offshore oil and gas engineering of the present invention is manufactured according to the following steps: extruding a chemically cross-linked polyolefin insulating layer 2 on the periphery of a 0.35mm tinned annealed stranded copper conductor 1 to form an insulating core , the insulated wire cores are twisted in pairs to form a pair of twisted wires, the twisted pitch of each pair of twisted wires is not greater than 120mm and all pairs of twisted wires use different twisted pitches; all pairs of twisted wires are 16 times the ratio of twisting pitch diameter to right-hand twisting to form the cable core, and the copper foil polyester composite tape shielding layer 3 is wrapped around the outer periphery of the cable core with the copper foil facing inward, and the inner side of the copper foil polyester composite tape shielding layer 3 is set There are tinned stranded c...
Embodiment 2
[0029]The high-temperature-resistant soft overall shielded instrument cable for offshore oil and gas engineering of the present invention is manufactured according to the following steps: extrude a chemically cross-linked polyolefin insulating layer 2 on the outer periphery of a tinned annealed stranded copper conductor 1 of 1.25mm2 to form an insulating core, and an insulating wire The cores are twisted in pairs to form a pair of twisted wires. The twisted pitch of each pair of twisted wires is not greater than 120mm and all pairs of twisted wires use different twisted pitches; all pairs of twisted wires are 20 times The ratio of stranded pitch diameter to right-handed stranding constitutes the cable core, and the copper foil polyester composite tape shielding layer 3 is wrapped around the outer circumference of the cable core with the copper foil facing inward, and the inner side of the copper foil polyester composite tape shielding layer 3 is provided with tin plating. Twist...
Embodiment 3
[0035] The high-temperature-resistant soft overall shielded instrument cable for offshore oil and gas engineering of the present invention is manufactured according to the following steps: extruding a chemically cross-linked polyolefin insulating layer 2 on the outer periphery of a tinned annealed stranded copper conductor 1 of 2.5mm2 to form an insulated wire core, and an insulated wire The cores are twisted in pairs to form a pair of twisted wires. The twisted pitch of each pair of twisted wires is not greater than 120mm and all pairs of twisted wires use different twisted pitches; all pairs of twisted wires are 24 times The ratio of stranded pitch diameter to right-handed stranding constitutes the cable core, and the copper foil polyester composite tape shielding layer 3 is wrapped around the outer circumference of the cable core with the copper foil facing inward, and the inner side of the copper foil polyester composite tape shielding layer 3 is provided with tin plating. ...
