What Is The Stainless Steel Explosion Resistant Cable Gland?

1. The application specification of the stainless steel explosion resistant cable gland

According to the standard of GB 3836.1-2010 Explosive Atmospheres: Equipment General Equipment, it is called “explosion proof cable entry device” (also known as “Incoming device”, “Explosion-proof cable seal connector”, “Explosion-proof cable gland”, “Explosion-proof connector”), the products are mainly used in the cable entry and extraction of all kinds of junction boxes, meters, electrical equipment and power equipment in explosive gas environment of petroleum, chemical industry, electric power, metallurgy, light industry, coal, building materials, fire fighting, automation control industries. Explosion-proof cable gland used for explosion proof and seal for the entry or extraction of the wire and cable in the junction box, instrument, electrical equipment, so that such equipment can isolate in internal and external, to achieve the purpose of explosion-proof electrical equipment shell parts.

2. Explosion-proof identification and product structure

In the purchase of explosion-proof cable gland, because the product is in direct contact with the explosive gas mixture surrounding , so the structure of the product must be safe and reliable,  meet the standard of GB 3836.1-2010 and pass strict testing to obtain explosion-proof marks. LEINUOER explosion-proof cable gland series to be launched all reach these requirements. Its product identification is divided into two parts: model identification and explosion-proof identification:

Stainless Steel Explosion Resistant Cable Gland is made of 8 components: hexagonal nut, middle part of the main unit, lower part of the main unit, shrink compressing ring, shield compressing ring, systolic ring, shield shrinking ring and O-ring, the main structure is  made of 304 stainless steel material, sealing ring is EPDM (Ethylene-Propylene-Diene Monomer) material, excellent selection of materials to ensure the protection of the product performance.

3. Precautions for use and maintenance

Explosion-proof cable gland is an independent test evidence equipment part which is closely associated with explosion-proof electrical equipment, we should pay special attention to such points when purchasing and using:

1. Pay attention to the product model, the thread standard and size should match the equipment;

2. Before installation, check whether the explosion-proof mark, explosion-proof certificate number and appearance of the product are defective;

3. Use the cable outer diameter to select the corresponding size of the product and sealing ring;

4. Pay attention to the protection of the explosion-proof  surface of the thread ;

5. Replace the aging and damaged seal ring in time;

6. Wrench should be used when connecting and installing all thread parts to ensure tightening.
