What is the cable gland? Some purchase list written on the list is very simple, write an explosion-proof cable gland, in fact, also called explosion-proof cable sealing joint, cable explosion-proof glenhead, but the name is not the same, the products are the same. The introduction device is added to the cable to play the role of waterproof, flame-proof, dustproof, fastening and pressing the cable.
Generally, there are several materials, the best is pure copper material, but because the price is much more expensive, the market share is not high. For example, the 304 and 316 stainless steel materials are widely used by enterprises and individuals. They are suitable for most environments, including salt resistance, acid and alkali resistance and corrosion resistance. 316 material is recommended for coastal areas with strong corrosion resistance, which has better wear resistance. There is a high price of brass nickel plating material, do not do explosion-proof requirements of nylon material, this is no longer repeated.
The structure of explosion-proof cable gland has been designed according to market demand, a variety of structural forms, there are simple unarmored cable form, single seal form,
Double seal form and armored cone ring form. Due to the construction site project site explosion-proof instrument box, explosion-proof equipment installation always designed to some special Design, therefore, the extension of the Structure of the Glenhead, each is not the same, but also are much the same.
We usually recommend the bad environment, it is must to use explosion-proof cable gland, like dust areas (wood shoulder, flour mills, cigarette factories, polishing workshop, etc.), corrosive environment (chemical industry, shipbuilding industry, chemical industry, etc.), as well as our daily access to the site (gas station, gas station, a LPG, etc.).
Danger is always over our environmental security, so we must strengthen the awareness of security, do not coziness, safety awareness is weak, it leads to a mistake, always beware, alert. We should not take things for granted when they are small. We should not take things for granted when they are complicated. We should not take things for granted when they are urgent and blind.
