Cable gland
Cable Glans is the cable sealing joint, most of them for the sealing joint is actually used to prevent dust and water, in some dangerous areas, sealing joint needs to choose explosion-proof sealing joint, its role is to prevent combustible gas into the head of the inside.
1. Basic Introduction
The main role is the cable fastening, protection and sealing. Fastening refers to locking the cable through the grant, so that the cable does not produce axial displacement and radial rotation, so as to ensure the normal connection of the cable. Protection refers to the cable through the wall, to prevent scratching and cutting. Sealed refers to the usual IP protection, that is, dust-proof waterproof, MB cable glands shall be up to IP68. There are also some special places to use them, such as shielded cable waterproof joints, suitable for cable with shield layer, for armored cable waterproof joints, for dangerous areas such as mines, such as explosion-proof cable waterproof joints.
2. Classification
According to the material is divided into metal products and plastic products, metal products, the vast majority of the industry using brass, in order to corrosion will be nickel plating. Also have the use of stainless steel materials, such as stainless steel 304, stainless steel 316, stainless steel 316L, etc. . Plastic products, now the industry mainly used nylon materials (PA6, PA66) also used PVDF and other materials;
3. The implementation of standards
