The decision to use an explosion-proof system is concerned with the prevention of sparks and heating. Gas may accumulate and create fires in the cable trays in oil and gas plant areas. Their free-flowing structure allows gas to escape. Chemical plants have risks like explosive gases, dusts, or vapors. It's serious business – around 15% of chemical plant explosions happen because of. Cable Trays have been permitted in the hazardous (classified) locations in the National Electrical Code for Class I (flammable vapor and gases) since the 1978 NEC and have been used extensively in chemical plants, refineries, and other types of facilities. International and North American requirements for cables and cable glands will be examined. Our hazardous location cable collection consists of cables that are both rugged and durable, including Halo-FlexTM cable, Armor-X® cable, and Aluminum Interlocked Armor (AIA). WHAT IS A HAZARDOUS LOCATION? Explosion or fire hazards exist due to the presence of flammable gases, combustible. Whether it is data cables from a gas detector or the cable protection on a power transmission unit, ABB hazardous area cable glands are designed and manufactured to meet the demands of rigorous and arduous operating environments in addition to ATEX and IECEx standards.
