Preformed tension clamp is a kind of power fittings specially used for overhead lines,the structure is very simple. The Preformed tension wire is twisted to form an empty tube, and the rear part is a preformed twist ring.Preformed tension clamps can generate a strong gripping force when it is wrapped around the conductor or the cable, and the twist ring is used to fix it on the insulating porcelain or the pole tower. The principle and structure of the Preformed tension clamps have unique performance and distinctive characteristics.
Features of Preformed Tension Clamps:
①Uniform force distribution: Preformado wire guy grip do not damage the conductors, and the force applied by the clamps to the conductors is evenly distributed, which improves the vibration resistance of the conductors and prolongs the service life of the conductors.
②Reduce the risk of wire breakage: Preformado wire guy grip can dynamically adapt to the slight displacement changes of the cable, disperse the instantaneous load impact, and reduce the risk of line fatigue and wire breakage.
③Sufficient gripping force: Preformado wire guy grip have a firm twisting ring, which can provide sufficient gripping force for conductors such as steel core aluminum stranded wire, aluminum stranded wire, and aluminum alloy stranded wire, and have a larger range of applicable conductor sizes.
④High tensile strength: Each conductor tension clamp has an additional Preformed length to ensure that the tensile strength can reach the rated breaking force of the conductor.
⑤Simple and efficient installation: Preformado wire guy grip are quick and easy to install, without any special tools, and can be completed by one person manually installing. Inspection can be done with the naked eye, and the appearance is simple and beautiful.
⑥Strong versatility: Preformado wire guy grip can be used with a variety of hardware.
There are many types of Preformed tension clamps, which can be divided into Preformed conductor tension clamps, Preformed ground wire tension clamps, Preformed wire tension clamps, etc., which bear the tension of the conductor (such as fixing and supporting the phase wire of the transmission line), the tension of the ground wire (such as OPGW optical cable or ordinary ground wire) and the tension of the wire (such as the wire of the pole or tower).
Preformed tension clamps and Preformed wire pullers produced by our company are made of high-strength materials, and the holding force can meet the national standard requirements. The materials used are exactly the same as those of the stranded wire. The products not only enjoy a good reputation in the domestic market, but also sell well in the international market, and are exported to more than 30 countries and regions.Vilun Electric Co., Ltd.has become a member enterprise of the China Chamber of Commerce for Import and Export of Mechanical and Electrical Products.
