SYC type upper element C-type wire clamp

1、 Product Overview:

The SYC series Shangyuan C-type wire clamp is one of our company's patented products. The Shangyuan C-type wire clamp is mainly used for 10kV overhead insulated conductors, aluminum stranded wires, steel core aluminum stranded wires in overhead distribution lines

Used for T-joints or jumpers in non load bearing positions. The upper C-type wire clamp is made of high-strength special aluminum alloy with good conductivity, and the structure adopts a reasonable C-type two main wedge blocks

Composition: When the main wedge block is subjected to external force, the wire is pressed between the clamp body and the two segmented wedge blocks. Due to the special C-shaped design principle of the main body of the wire clamp, when the wire expands and cools

Time lapse refers to the elastic properties inherent in the main body of the wire clamp, which always maintain a persistent and constant contact pressure between the clamp and the wire. It varies in contact pressure with changes in external environment and load conditions

The force remains unchanged, meeting the optimal performance requirements in the connection.

2、 Installation instructions for C-type wire clamp

C-type clamps are non load bearing electrical connection fittings and cannot be used as load-bearing fittings; Can only be used for wire connections, jumpers, "T" connections, and transformer down conductors. Wire clamps are suitable for voltage levels of 10kV, 35kV, 110kV, 220kV, 380kV, and can be used for aluminum aluminum, copper copper, and iron iron connections. No need for aluminum tape wrapping.

1. Determine the model: Carefully check that the wire and clamp are consistent, such as SYC-822 LGJ185-LJ120/95, LGJ95 is represented as: LGJ185 vs. LJ (TJ) 120 or

The connection between LGJ185 and LJ (TJ) 95 or LGJ185 and LGJ95. As shown in Figure (1)

2. Determine the size of the wire: Due to the consideration of meeting the fit of different wire diameters in the design of the wire clamp, the inner curved surfaces on both sides of the hinge block have different sizes, and the large curved surface is matched with the large wire; Small curved surface with small wire. Regulation: The mother block is the main line, and the male block is the branch line. Take out the hinge block and make it arch (the two hinge blocks rotate at a certain angle). As shown in Figure (2)

3. Place the wires and bolts properly: Place the wires into the "C" cable tray and arrange them in an arch shape outward according to their size. Insert the bolt from the back of the "C" part, so that the bolt is located at the top of the hinge block

Tighten the bolt with a wrench in the middle position. As shown in Figure (3, 4) 4. Confirm that it has been installed: When tightening the bolts, there should be a clear sense of force on the last few threads. Flatten the hinge block and press it against the "C" part. The 'C' component should have slight deformation. As shown in Figure (5)

Note: After installation, pull or pull the two wires by hand to see if they have been tightened.

5. Disassembly: Loosen the bolt, insert a screwdriver between the hinge and the "C" part, and pry upwards with force to arch the hinge block upwards. As shown in Figure (6)
