The fire resistant cable industry has evolved from the most rigid design of Mineral Insulated Copper Cladded Cable (MICC) to the flexible Fire Resistant Mineral Insulated Cable (FRMI). Building designs can be compromised with cheaper cable insulation such as XLPE or PVC. This has undermined and defeated the purpose of fire performance cable, increasing the risk of flame propagation and hazardous gas bulid-up in the event of a fire. Today, Structures are getting taller, with more complex building facilities and more critical space utilization. Hence, the selection criteria of fire resistant cable is most vital in the preventation and full protection in the event of an untoward situation.
The selection of cable insulation and sheath materials determines the performance characteristic of the cable during fire. The window of safety margin is directly corresponding to the degree of operating temperature, flammability index, smoke and toxicity level as well as the halogen gas content. Hence, it is vital to ensure consitency in product quality by evaluating the manufacturer's reputation as well as the product's third party accredited testing & certification bodies.
As one of the key players in the fire resistant cable industry, we are fully aware that cost is always an important factor in all project design cosideration. However, we also observer that this factor can be magnified at different decision-making levels and could be confusing to project owners. Copper, being the key material consistutes ore than 50% of the entire cable construction is a price transparent commodity. What usually determine the cost of the fire resistant cable is the insulation material used and the value of its production processes. In today's price competitive market, the type of insulation material is commonly overlooked and compromised in many installations. We strongly believe that fire safety should never be compromised in any engineering design.
