Wire and cable are essential in industrial production, and are often in various harsh environments, so safety protection is particularly important. Corrugated hoses, cable glands, hose joints, plastic waterproof boxes, etc., are ideal accessories for protecting cables.
As we all know, in the cable line, if there is a fault accident, it will affect the safety of the equipment and endanger the life safety of the operator. However, the source of these accidents is actually 50% related to the cable accessories. It is conceivable that the cable joints It plays a pivotal role in the safety of the entire power transmission and transformation!
Usually, cable joints need to have waterproof, dustproof, acid resistance, alkali resistance, insulation and other properties to face various harsh environments. As an accessory in the equipment, it shoulders the important responsibility of transmission, and cannot tolerate sloppy. In practical applications, Water ingress and dust prevention have always been a problem for everyone, because not only will the service life be shortened, but also serious accidents may occur; the same crucial problem, in some special industries, they have another requirement for cable joints.
For a long time, explosion-proof products have implemented an explosion-proof certificate system, that is, all electrical products used in explosive hazardous places must obtain an explosion-proof certificate before they are allowed to use, which has become an industry practice. The explosion-proof certificate is stipulated in the appendix of the mandatory national standard GB3836.1-2010. Therefore, manufacturers producing explosion-proof products must apply for the explosion-proof certificate. But at present, many unscrupulous merchants take advantage of a loophole in the explosion-proof certificate system, that is, the explosion-proof inspection unit can detect whether the samples sent by the manufacturer meet various explosion-proof standards, but they cannot know whether the manufacturer has the ability to produce or mass-produce it. Standard explosion-proof products, which not only affects the market but also brings serious safety hazards!
