Power Fittings Manufacturers' Overview Of Power Fittings Products
Spiral pre-twisted wire power hardware products include: pre-twisted tension clamps, which can replace traditional bolt-type tension clamps, wedge-type tension clamps, and compression-type tension clamps; its salient features: pre-twisted tension clamps The tubular structure formed by the two legs of the wire is naturally wrapped around the conductor. The clamp has high strength and reliable grip. The grip strength of the clamp is not less than 95% CUTS (calculated breaking force of stranded wire); the stress of the clamp on the conductor is evenly distributed without damaging it. The wire improves the vibration resistance of the wire and greatly extends the life of the wire; it is simple to install and easy to construct, which can greatly shorten the construction time. No special tools are needed (no need to carry bulky generators and equipment tools), and it can be completed by one person Operation; the installation quality of the wire clamp is easy to ensure and can be inspected with the naked eye without special training; it has good corrosion resistance and the material is exactly the same as the wire, ensuring that the wire clamp has strong resistance to electrochemical corrosion.
Pre-twisted suspension clamp: a hyperbolic waist drum-shaped hoop made of EPDM rubber. The hoop is wrapped with aluminum alloy pre-twisted wire. Outside the pre-twisted wire, it is equipped with an aluminum alloy shell and U-shaped Composed of cards, it can replace various types of traditional boat-shaped wire clamps. Its remarkable feature is that the stress at the suspension point is distributed to the entire length of the pre-twisted wire, effectively reducing the static pressure on the wire and the dynamic stress caused by breeze vibration, avoiding It prevents the wire from being damaged, greatly improves the fatigue resistance of the wire, and extends the service life of the wire; at high voltages above 345KV, the end of the pre-twisted wire adopts parrot-beak structure technology to ensure that no discharge occurs; the pre-twisted wire can also provide Reliable gripping force, withstands high unbalanced loads, thereby avoiding wire slippage; the rubber and shell are made of non-magnetic high-strength materials, and are designed with a streamlined structure, which can reduce corona generation and hysteresis loss; the entire wire clamp is lightweight , high strength, using it can save both material energy and electric energy, resulting in benign economic benefits; at the same time, it can enhance the stiffness of the wire suspension point and increase the radius of curvature. The single fulcrum line clamp can reach a steering angle of 30 degrees, and the double fulcrum can The steering angle can reach 60 degrees, which effectively solves the long-standing suspension problems of high drop and long-span projects.
Pre-twisted splicing hardware: There are pre-twisted conductor splice strips, pre-twisted jumper splice strips, pre-twisted ground wire splice strips, and pre-twisted pull-wire splice strips. Depending on the situation, it can replace the traditional clamps for crimping continuous pipes and crimped pipes, parallel groove clamps, and T-joints; it is generally composed of spiral pre-twisted wire, sand, conductive sand, and glue. Depending on the requirements, the original machinery can be restored performance, electrical performance, or restore mechanical and electrical properties at the same time; the material of the pre-twisted wire is the same as the conductor material, thus ensuring good corrosion resistance; the pre-twisted structure can also disperse concentrated stress evenly, extending the life of the conductor; The installation is quick, simple and convenient. There is no need to carry equipment or tools. It can be installed with bare hands. At the same time, the entire cable clamp is light in weight and elastic, has strong vibration resistance, long service life, safety and reliability, so it can also save a lot of money in project construction. Human and material resources.
Pre-twisted protective strip: used to protect conductors from vibration, Pre-insulated sleeve, friction, wear, arc and other damage. It is often installed in ship-type clamps and on pillar insulators. It can also be used as a repair strip to repair damaged conductors. It restores its original mechanical strength and conductive properties; its structure is simple, a group of pre-twisted wires form an empty tube and are wrapped around the conductor to hold the conductor tightly, dispersing the stress on the conductor, improving the conductor's anti-vibration ability, extending the service life of the conductor, and installing Quality is also easy to guarantee.
