C-type clips are mainly used for T-connection live jumpers in overhead distribution lines (1KV-20KV) overhead insulated conductors, aluminum stranded wires, steel stranded wires and copper conductors at non-stress positions. The wire clip is made of high-strength special aluminum alloy with good electrical conductivity. When the wire is thermally expanded and contracted, the elasticity of the C-shaped structure always maintains a lasting and constant contact pressure between the clip and the wire, and with the change of the external environment and load conditions, the contact pressure remains unchanged, which satisfies the continuous The best requirements for connection. The structure can be divided into two categories according to the way of fixing the wire: wedge hinged fixed type and crimping clamp clamping type. 1) Clamping type is to use a pressure clamp equipped with a suitable crimping die, put the wire into the groove of the corresponding ruler of the selected C-type clamp, and apply external force to the pressure clamp to shrink and wrap the C-type clamp. On the periphery of the wire, this is the way to complete the current connection function of the wire. Usually, according to the different grooves, it can be divided into more categories. The high-performance hydraulic clamp is used for crimping, and the hydraulic clamp can automatically prompt the pressure relief, so as to ensure the constant and uniform pressure applied during installation. It avoids the various hidden dangers caused by the uneven construction quality caused by the uneven physical strength and quality of the construction personnel. 2) The hinged hinged structure of the wedge block and the fixed element press the wire between the clamp housing and the wedge block. The fixed element overcomes the disadvantage that the nut slides to the left and right sides when the screw is tightened and needs to be corrected many times, reducing the installation. The influence of human factors at times ensures that the whole has the function of uniform and uniform force. It does not damage the wire during installation and disassembly; it can be reused many times, has the same life as the wire, and can reduce labor intensity and improve work efficiency. It is an environmentally friendly and energy-saving item. Performance When the C-type clip is used for the current connection of the wire, the crimping is tight and the connection joint is integrated. After the crimping, the sleeve is fully covered with the wire, and the current conduction is evenly distributed. The resistance is only micro-ohm level, and the temperature is low and High tensile strength, which can reduce the failure rate by more than 80%. Make the line have stable and good contact performance, free maintenance, reduce maintenance costs, reduce energy consumption, and save energy. Features: 1. Contact performance: large contact area, constant clamping force, and DC resistance ratio between 0.85-0.9. 2. Overload capacity: the overload capacity reaches more than 2 times of the rated current. 3, firm performance: high-strength material. The stainless steel bolts are fastened, the connection is reliable, and it will never fall off. 4. Thermal cycle performance: The thermal cycle performance is good, always running below the DC resistance ratio of 1. 5. Installation: easy to install and disassemble, suitable for high-altitude work. 6. Energy-saving performance: Made of high-strength special aluminum alloy, no electromagnetic loss, anti-corrosion, anti-oxidation. Application range: C-type clips can be used in electrical lightning protection grounding projects that require firm connection and non-detachable connection, such as power grounding grids, lightning protection grounding grids, etc. The UL standard lists: Clamping type clamps can be used as the connection between grounding stranded wires, grounding round solid core conductors, copper grounding rods, etc. directly buried in the grounding system, and can also be used for the connection of power cables. In particular, the connection of conductors in concrete or soil has various forms and is convenient for construction and installation. Wedge-type articulated C-type clamp is suitable for T-connection and parallel-line connection in non-tension positions such as steel-cored aluminum stranded wire, overhead insulated wire, aluminum stranded wire, aluminum-clad steel wire, and copper wire on power transmission and distribution lines. Flow connection and jumper connection are non-load-bearing connection fittings. Such as: aluminum-aluminum, copper-copper connection, copper-aluminum transition. The installation does not need to use aluminum wrapping tape, and the operation is simple and convenient.
