Wire and power cable use errorsThis is a considerable number of users, and even some companies use overhead cable presence of the more common errors. Some users save money, ignore safety, specifically pick those low prices, quality is not guaranteed, accidents big inferior overhead cable. We know that because of safety wire cable and other factors, res...
Provisions for welding tongs and welding cablesWelding clamp and welding cable shall comply with the following provisions:1. The holder shall ensure that any inclination to the clamping electrode, and easy replacement of electrodes.2. The holder must have good insulation and heat insulation ability. Handle the best thermal performance should be goo...
Competitive analysis of China's wire and cable industryAt this stage, the product structure of the wire and cable industry is more prominent problems is the supply of ordinary cable products, high-end product supply is insufficient, the product structural contradictions. In the medium and low voltage wire and cable market, the dom...
Selection of welding cablesWelding cable refers to the connection machine a primary side coil and a holder, earth clamp to form the welding circuit cable.In order to make the welding operation convenient and flexible, soft welding cable should be used, especially near the welding area of 2 ~ 3m. The wire should be as far as possible to choose soft cable. If...
