Fireproof cable trays in Brunei are typically made from hot-dip galvanized steel with minimum 2mm thickness, comply with local DES-approved standards, and can be enhanced with fire-resistant coatings or tapes for added protection.

Material and Dimensions

Cable trays used in Brunei are generally manufactured from hot-dip galvanized steel to ensure durability and corrosion resistance. Standard dimensions include widths of 200mm and heights of 50mm, with lengths of 3 meters per section. The steel thickness is typically ≥ 2mm, and slotted designs are common to allow ventilation and cable management (Berakas Power Company BQ) .

Fireproofing and Protection

To achieve fire resistance, cable trays can be coated or wrapped with specialized fire protection products. Examples include FLAMMOTECT-A fire protection coating and DG-CR 0.7 fire protection tape, which form a protective shield around cables and trays, preventing flame propagation and maintaining functionality during fire incidents. These solutions are suitable for indoor and outdoor installations, including high-risk areas such as hospitals, power stations, substations, and industrial facilities .

Compliance and Standards

All cable trays installed in Brunei must comply with the Department of Electrical Services (DES) approved product list. Products not listed by DES are not acceptable for use. Compliance includes adherence to mechanical and electrical standards, CE marking, and third-party certifications such as UL, IMQ, or LCIE for fire resistance and quality assurance .

Installation and Handling

• Materials must be individually packed in protective wooden crates for transportation and labeled with project details, manufacturer, and date of manufacture .
• Installation should follow manufacturer guidelines to avoid exceeding specified voltage, current, or temperature limits .
• Fireproof coatings or tapes should be applied according to manufacturer instructions to ensure maximum fire resistance and environmental protection against UV, moisture, and chemicals .

Local Suppliers

Brunei has local suppliers and manufacturers such as Brilltech Engineers Pvt. Ltd., which provide standard and customized cable trays meeting industry and fire safety requirements . By combining DES-approved galvanized steel trays with fire-resistant coatings or tapes, installations in Brunei can meet both mechanical durability and fire safety standards, ensuring reliable power and communication systems even under emergency conditions.
