Cable Clamp Type And Function

Power line distribution hardware fitting supplier to share with you:

(1) Tension clamps are used for corners, connections, and terminal connections. Spiral aluminum clad steel wire has strong tensile strength, no concentrated stress, and plays a role in protecting and assisting vibration reduction of optical cables. Tension clamp is used to fix the conductor or lightning conductor to the non-linear pole tower tension insulator string. It acts as an anchor and is also used to fix the wire of the tower.、

(2) The overhanging clamp is a common stereotyped product. A U-bolt style fixed overhang (usually called a ship-type clamp) is retained. It is composed of a U-bolt and a hull. The other is a pre-twisted suspension clamp, which is widely used in China.

Old-fashioned ship-type wire clip: This kind of wire can be used for lightning conductors. It can withstand the installation load of the conductor within the vertical span, and does not allow the clamp to slide or leave the insulator string when the line is running normally or is disconnected. The bearing pressure of the pole tower using this clamp is large.

(3) The puncture clip has the characteristics of easy installation, low cost, safety, reliability, and maintenance-free. No need to cut off the main cable, no need to strip the cable insulation layer to make cable branch, the connector is completely insulated, can be live work, can be branched at any location on the cable. It is an insulating fitting, and no terminal box or junction box is needed. And the connector is resistant to twisting, shockproof, waterproof and corrosion-proof. The use of insulation piercing clamps for cable branching has obvious comprehensive benefits and is more cost-effective than traditional connection methods in the past.

(4) Equipment clamps, which are mainly used for the connection of the down conductors of the substation busbars to the outlet terminals of electrical equipment (such as transformers, circuit breakers, isolation headers, wall bushings, etc.), because the outlet terminals of common electrical equipment are copper There are two types of steel and aluminum, and the bus bar leads are divided into aluminum core wires and steel core aluminum stranded wires, so the equipment clamps are divided into two series: aluminum equipment wire flats and copper-aluminum transition equipment clamps.

Application of cable fasteners:

Fasteners are a type of mechanical parts used for fastening connections and are widely used. A variety of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a large variety of specifications, different performance and uses, and the standardization, serialization, and generalization of the species is extremely high. Therefore, some people refer to a class of fasteners that have national standards as standard fasteners, or simply as standard components. Set bolts are the most widely used mechanical foundation. With China's entry into the WTO in 2001 and entering the ranks of international trading powers. China's fastener products are exported to a large number of countries in the world, and fastener products from all over the world also continue to flood into the Chinese market. Fasteners, as one of the products with a large import and export volume in China, are in line with international standards. It is of great practical significance to promote the development of Chinese fastener companies into the world and promote the full participation of fastener companies in international cooperation and competition. Strategic significance. Due to the specific requirements of each specific fastener product's specifications, dimensions, tolerances, weights, properties, surface conditions, marking methods, and acceptance inspection, marking and packaging items.

Common detection equipment:

The most important link in the development and design of fasteners is quality control. There are several major barriers from incoming materials to finished product shipments. These major barriers have different inspection methods. First of all, the feed is related to appearance, size, element, performance, detection of harmful substances, etc .; the process is more about appearance, size, percussion experiment, forging streamline; heat treatment is more about appearance, hardness, torque, tensile force , Metallography, etc .; the surface treatment is more some hydrogen embrittlement test, coating, salt spray, etc., including shipment of a harmful substance detection. In terms of size and appearance inspection, two-dimensional elements, contour measuring instruments, three-coordinate measuring instruments, and image sorting machines (this is a full-selection machine) are common; in mechanical and chemical testing, there are mainly hardness machines (Rockwell and Vickers) ), Tensile machine, metallographic microscope; material testing, there is a spectrum analyzer, salt spray tester.
