Embodiment 1

[0035] refer to Figure 1-4 and Figure 8 , a fiber-reinforced resin-based composite core overhead insulated cable, comprising a fiber-reinforced resin-based composite core 1, a plurality of heat-resistant aluminum alloy single wires 2 arranged on the outside of the fiber-reinforced resin-based composite core 1, and a plurality of heat-resistant aluminum alloy single wires 2 The outer side is provided with the same shielding layer 3, and the inner wall of the shielding layer 3 is bonded with a plurality of armored sleeves 8 distributed in a circular array. The armored sleeves 8 are made of metal materials, and the outer wall of the armored sleeve 8 is fixed with an air outlet pipe 9. The inner wall on both sides of the air outlet pipe 9 is provided with a first chute 10, the first chute 10 is slidably connected with a first slider 11, and the first slider 11 and the inner wall of the first chute 10 are fixed with the same The first spring 12, the same exhaust column 13 is fixed...

Embodiment 2

[0043] refer to Figure 5-7 , a fiber-reinforced resin-based composite core overhead insulated cable, the floating mechanism includes an orientation plate 29, the orientation plate 29 is fixed to the bottom inner wall of the installation opening 19 by bolts, and an orientation opening 30 is opened on one side of the orientation plate 29, and the orientation opening 30 slides Connected with an orientation block 31, the side of the orientation block 31 close to the sleeve 20 is fixed with a frame rod 38 by bolts, the cross section of the frame rod 38 is arranged in an L shape, and the other side of the frame rod 38 is fixed with a first pole 39 by bolts, the second A rod 39 and the inner column 21 are fixed by bolts, and the inner wall at the bottom of the installation port 19 is connected with a reciprocating screw rod 34 through bearing rotation. The reciprocating screw rod 34 is threaded with a sleeve block 33. The same connecting rod 32 is fixed by bolts, the top of the reci...

Embodiment 3

[0047] refer to Figure 9-10 , a fiber-reinforced resin-based composite core overhead insulated cable, the bottom of the inner column 21 is bonded with a permanent magnet 45, the bottom inner wall of the embedded groove 28 is fixed with an electromagnet 46 by bolts, and the bottom inner wall of the installation port 19 is fixed with a frame plate 49 by bolts, The top of the frame plate 49 is fixed with a coil winding 50 by bolts, the first shaft 22 is sleeved and fixed with an inner sleeve 47, and the inner sleeve 47 is sleeved and fixed with a ring magnet 48.

Abstract

The invention belongs to the technical field of cables, and particularly relates to a fiber-reinforced resin-based composite core aerial insulated cable which comprises a fiber-reinforced resin-based composite core, a plurality of heat-resistant aluminum alloy single wires are arranged on the outer side of the fiber-reinforced resin-based composite core, and the same shielding layer is arranged on the outer sides of the heat-resistant aluminum alloy single wires. A plurality of armoring sleeves are bonded to the circumferential inner wall of the shielding layer, air outlet pipes are fixed to the arc outer walls of the armoring sleeves in a penetrating mode, first sliding grooves are formed in the inner walls of the two sides of each air outlet pipe, first sliding blocks are slidably connected into the first sliding grooves, and the same first spring is fixed between the first sliding blocks and the inner walls of the first sliding grooves through bolts; the same exhaust column is fixed between the two first sliding blocks through bolts, a plurality of exhaust holes are formed in the bottom of the exhaust column, and the armored sleeve is filled with dry powder. According to the invention, the air pressure in the armoring sleeve is suddenly increased through high temperature generated by fire, and then dry powder in the armoring sleeve is sprayed out to extinguish fire, so that the fireproof effect is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a fiber-reinforced resin-based composite core overhead insulated cable. Background technique [0002] The cable is usually twisted by several or several groups of wires (at least two in each group), similar to a rope cable, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with Highly insulating overlay. Cables have the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, and aluminum alloy cables. etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] In the connection part of the cable, the...
