BSM7 cast fireproof and waterproof busway is an independently developed busway by our company. The shell is made of special resin material and completed according to a special formula and process. This series of products has the functional characteristics of acid corrosion resistance, waterproofing, and fireproofing, and the protection level reaches the highest level IP68， Mainly used in special working environments, it can work continuously in water and also meet the requirements of fire protection environments. This series of products has passed rigorous experiments such as GB7251.6-9.101 to prevent flame propagation and GB7251.6-9.102 to verify fire resistance performance in building structures, fully meeting the requirements. By adding fire-resistant facilities to this structure, it can be upgraded to a fire-resistant busway. After being verified for its fire-resistant performance by the National Fire Inspection Center of the Ministry of Public Security, it ensures the integrity and protection level of the circuit for a long time under flame conditions, meeting the standards of fire-resistant busways.
