Problems solved by technology

[0002] With the opening of a new round of rural and urban grid transformation, the State Grid has greatly increased the bidding volume of parallel bundled overhead insulated cables in the product bidding, because parallel bundled overhead insulated cables have small line reactance, less space, and simple line structure. It has the advantages of reducing the risk of electric shock, convenient erection, and low overall cost. However, the overhead insulated cables currently used cannot meet the needs of conventional parallel clustered overhead insulated cables for areas that require large lengths such as forest areas and mountainous areas. , in this regard, it is of great significance to provide a parallel bundled overhead insulated cable with high production efficiency, long service life, low overall cost and easy to promote and its production process

Embodiment 1

[0019] Such as figure 1 or figure 2 As shown, a carbon fiber reinforced core aluminum conductor parallel cluster overhead insulated cable, it includes a compacted conductor, and the compacted conductor is made of a round carbon fiber wire 1 and a special-shaped duralumin wire arranged on the outer wall of the round carbon fiber wire 1 2 twisted, the outer wall of the compressed conductor is provided with an insulating layer 3, the insulating layer 3 is connected with a connecting rib 4, and the upper side of the connecting rib 4 is provided with a Peugeot wire 5.

[0020] The present invention is a 3-core or 4-core parallel cluster overhead cable, which has the following advantages when used: 1. High tensile strength, ① Due to the use of circular carbon fiber filaments, the overall breaking force of the cable can be greatly improved, and the installation of the cable can be increased. spacing, to meet special requirements and reduce installation costs; ②The quality is relati...

Embodiment 2

[0022] A production process of parallel bundled overhead insulated cables, the production process of the parallel bundled overhead insulated cables includes the following steps: Step 1: wire drawing, using a wire drawing machine, and through an improved drawing die, drawing according to the conductor stranding structure Make profiled aluminum monofilaments; step 2: stranded wires, use carbon fiber filaments as the load-bearing wire and the profiled aluminum monofilaments obtained in step 1 are arranged according to a certain structure and then concentrically twisted to form a conductive core, and a diamond mold is used Carry out secondary round compaction; Step 3: Extrusion, use the polyethylene material after irradiation cross-linking to extrude the conductor wire core through an extruder; Step 4: Cross-linking, use the insulating material obtained in Step 3 The conductor wire core of the first layer is irradiated and cross-linked; the cross-linking time is 2-4h.

Abstract

The invention relates to a parallel bundle-assembled overhead insulation cable and a production process thereof. The parallel bundle-assembled overhead insulation cable comprises compression conductors, the compression conductors are formed by twisting of circular carbon fiber yarns and irregular hard aluminum wires arranged at outer walls of the circular carbon fiber yarns, outer walls of the compression conductors are provided with insulating layers, the insulating layers are connected with connecting ribs, and the upper surfaces of the connecting ribs are provided with marking lines. The production process of the parallel bundle-assembled overhead insulation cable comprises wire drawing, wire twisting, extrusion molding, and crosslinking. The cable and the production process thereof are advantageous in that the production efficiency is high, the service lifetime is long, the overall cost is low, and the promotion is facilitated.

Description

technical field [0001] The invention belongs to the technical field of cables and wires, and in particular relates to a parallel bundled overhead insulated cable and a production process thereof. Background technique [0002] With the opening of a new round of rural and urban grid transformation, the State Grid has greatly increased the bidding volume of parallel bundled overhead insulated cables in the product bidding, because parallel bundled overhead insulated cables have small line reactance, less space, and simple line structure. It has the advantages of reducing the risk of electric shock, convenient erection, and low overall cost. However, the overhead insulated cables currently used cannot meet the needs of conventional parallel clustered overhead insulated cables for areas that require large lengths such as forest areas and mountainous areas. In this regard, it is of great significance to provide a parallel bundled overhead insulated cable with high production effic...
