Electrical Works

Charges include the supply and application of fire-retardant cable coating for HV, MV, or LV electrical cables in the 11 kV Sub-Station. The coating shall be a latex-based/water-based intumescent formulation, designed to prevent flame propagation along single or grouped electrical and communication cables. Compliant with IEEE 383, IEEE 1202, IEC 60332-3, and BS 476 standards, the coating forms a carbonaceous barrier when exposed to heat, effectively restricting both horizontal and vertical flame spread and ensuring up to 2-hour circuit integrity. It shall be compatible with new or existing cable installations and ideal for critical power and communication systems, including cable trays and vertical risers. The paint shall be thixotropic for high-build application, with high solids for better coverage, non-halogenated, flexible, auto-bonding, water and weather resistant, and low abrasion to ensure longer pump life and reduced maintenance. Prior to application, cables and support structures shall be thoroughly cleaned of dust and dirt, degreased with a neutral cleaner, and surrounding floors, walls, and equipment properly masked.

The coating shall be applied evenly to all exposed surfaces, with subsequent measurement of layer thickness to ensure compliance. After curing, masking materials shall be removed and the installation area cleaned. This protective measure is critical, as electrical cables are among the most flammable materials in a facility; untreated PVC cables can propagate fire and release lethal hydrochloric gas, which when combined with water forms hydrochloric acid, potentially damaging electronics and infrastructure.

Cable Spray is formulated to adhere well to virtually all cable jacketing materials and may be applied using airless spray equipment or with a brush. SpecSeal® CS105 Cable Spray is very high in solids (by volume) and offers the highest coverage rates of any product of this type. SpecSeal® CS105 Cable Spray dries to form a flexible shield against the propagation of fire. Its premium latex binder system is totally resistant to water and will not re-emulsify after drying. SpecSeal® CS105 Cable Spray does not contain inorganic fibers, asbestos, or solvents. Applications SpecSeal® CS105 Cable Spray is primarily designed for the protection of grouped electrical, data, or communications cables in cable tray or racked cable applications to limit the spread of fire. Specifications

The single component fire protective cable coating shall be a water-based ablative elastomer that will also intumesce. The coating shall dry to form a flexible, water and weather-resistant film and shall not contain solvents, asbestos, or inorganic fibers. The coating shall be thixotropic and shall be capable of being applied by brush application or by airless spray. The approved coating shall be FM Approved Class 39
