The double parallel groove clamp is used for connecting aluminum stranded wires or steel-cored aluminum stranded wires with middle and small cross sections and steel stranded wires of overhead ground wires at positions not bearing tension, and is also used for jumper connection of non-linear towers. The power engineering material (hardware) connecting wires are connected with each other and mainly used for power line engineering. The parallel groove clamp is non-bearing type, mainly comprises 3 types of bolt type parallel groove clamp, H type (or C type) parallel groove clamp and wedge type parallel groove clamp, wherein the bolt type parallel groove clamp is divided into an equal diameter parallel groove clamp and a reducing parallel groove clamp.
The double parallel groove clamp can adopt a bolt type parallel groove clamp, a wedge type parallel groove clamp or an H type parallel groove clamp.
The bolt type parallel groove clamp is made of a plate-plate structure and an aluminum alloy material, a connected wire is fixed in a clamping plate with grooves at the upper part and the lower part by the fastening pressure of a bolt to complete connection, and then the connection is transmitted by a flat gasket and a spring washer to provide a uniform and constant pressure effect for the connected wire. Sometimes, in order to ensure the operation reliability, a mode that two or 3 wire clamps are connected in parallel at equal intervals is adopted during line construction. The holding force of the bolt type parallel groove clamp on the wire is about 10% -20% of the calculated breaking force of the wire.
The bolt type equal-diameter parallel groove clamp is generally only used for connecting wires with the same diameter, the allowed wire span generally comprises two adjacent specifications, for example, the section of the wire suitable for the JB-4 parallel groove clamp is 185mm2And 240mm2Two kinds, so the structure adopts symmetrical design.
The wedge-shaped parallel groove line material is generally forged aluminum and consists of an arched body and a wedge block, and gun-shaped special tools are used for installation or disassembly but cannot be reused. The inclination of the two side edges of the wedge block is the same as that of the body, so that the lead is uniformly stressed in the contacted section and self-locking among materials can be established; the arcuate body provides the spring force necessary to maintain a stable pressure. The curvature radius of the inner groove of the arch body and the radius of the outer groove of the wedge block are slightly larger than the radius of the maximum applicable lead. When the wedge block is installed, two continuous straight wires are put into corresponding positions on two sides of the body, the wedge block is pushed to the position of the mark line by manpower, and then a gun-shaped special tool is triggered to generate instant thrust to press the wedge block into a working position. The pressure on the wedge block is mainly determined by the dosage in the special bullet, and the influence of human factors on the installation quality is reduced, so that the installation consistency of the wedge type parallel groove clamp is better. The wedge-shaped parallel groove clamp can be connected with two wires with equal diameter and different diameter. The grip force of the wedge-shaped parallel groove clamp on the wire is about 20% -45% of the calculated breaking force of the wire.
The H-shaped parallel groove clamp belongs to a compression type structure, and is made of pure aluminum or aluminum alloy materials and cannot be disassembled after being installed. The clip is so named because the clip cross-section is similar to the letter H. The wire clamp and the two connected wires can be pressed into a whole by special hydraulic pliers. The contact part is in an elliptic cylinder shape after compression joint, and the appearance is compact. Similar to a wedge-shaped parallel groove clamp, the compression process of the clamp is controlled by the output pressure of a hydraulic clamp, and the manual influence is small. The H-shaped parallel groove clamp can be connected with two wires with equal diameter and different diameter, and the span of the wires in the same groove is generally 3-4 specifications. When the H-shaped parallel groove clamp is connected with a lead, aluminum on the inner wall of the clamp generates plastic deformation due to annular stress and is embedded into a twisting gap on the outer layer of the lead, the effective contact surface is large, and the holding force of the H-shaped parallel groove clamp on the lead is about 40-65% of the calculated breaking force of the lead.
