Fireproof cloth for distribution boxes
The flexible cloth can nestle around cables, conduits and trunking by cutting spaces into the cloth. In the event of fire, the intumescent cloth expands to create a fire seal, preventing the rapid spread of fires. Fire resistant cover with intumescent lining to protect electrical consumer units Common household electrical consumer units (ECUs) are an essential mains control of a home's energy supply. However, they are susceptible to overloading, causing dangerous fires and harmful smoke spreading within. ABB offers an innovative enclosure system for fire prevention, which is constructed of fireproof materials, features optimum technology and is available in a variety of economical designs. A wide range of wall enclosures (flush/surface/enclosure) and floor-standing enclosures (surface) are. Our fire protection hoods are designed for preventive fire protection in the storage and logistics of flammable media, as well as for the protection of valuable goods. The highly durable material. Sometimes referred to as fireproof fabric, fire resistant, flame retardant fabric or flame resistant fabric, our fire retardant fabrics include Industrial 18oz Vinyl, Sunforger Army Duck, and Duvetyne— see these products below. It remains non-flammable upon contact with open flame and performs well under continuous exposure to temperatures of up to 500 °C, withstanding even higher short-term peaks depending on the coating. Choose from our selection of fire cloth, including fabric, protective barriers, and more. -
