Fire-Survival Cables

UKB is a leading manufacturer and supplier of Fire-Survival Cables

UKB Electronics manufactures technologically advanced Fire-Survival Cables, also known as Circuit Integrity Cables. These cables are engineered to remain operational for a specified duration during a fire, ensuring that critical life-safety and firefighting systems function when they are needed most. Our cables are rigorously tested to leading fire performance standards like BS 7846 and IEC 60331.

Product Anatomy

The core of a fire-survival cable is its unique multi-layer construction. The copper conductor is first wrapped in a primary fire barrier of mica glass tape. This layer provides exceptional thermal insulation, maintaining circuit integrity even in direct flame. This is then covered by high-grade, cross-linked insulation and finally sheathed in a Low Smoke Zero Halogen (LSZH) compound, which minimizes toxic gas emission in a fire.

Key Features & Customisation Options

Circuit Integrity: Certified to maintain operation during fire as per IEC 60331 and BS 7846.
Enhanced Safety: Low Smoke Zero Halogen (LSZH) construction reduces harm to people and equipment.
Flame Retardant: Complies with IEC 60332-3, preventing the spread of fire along cable routes.
Robust Design: Engineered to withstand mechanical shock and water spray during fire conditions.
Applications: Mandatory for emergency lighting, fire alarms, PA systems, smoke extractors, and water pumps.

Integrated Manufacturing Capabilities

The life-saving reliability of our cables stems from our integrated manufacturing processes:

Specialized Taping Application: We utilize precision taping machines to apply the critical mica glass fire barrier, ensuring complete and consistent coverage for maximum circuit integrity.
LSZH Compounding: Our in-house compounding facility produces the advanced Low Smoke Zero Halogen (LSZH) materials used for insulation and sheathing, giving us full control over their fire performance properties.
Cabling & Armouring: Our integrated facility assembles the complete cable, including optional armouring, ensuring it meets the robust mechanical requirements of a life-safety product.
