Product Description
NG-A(BTLY) Flexible Mineral-Insulated Cable 0.6/1kV for Critical LV Fire Circuits
NG-A (BTLY) is a low-voltage mineral-insulated fire-resistant cable suitable for critical power circuits in buildings and infrastructure. It is designed for safer cable lines, emergency feeders, and critical services where flame retardancy and reliability are procurement priorities.
For life-safe circuits, the right cable is a vital component of the protection system. NG-A (BTLY) is suitable for low-voltage lines, ensuring the reliability of critical services in fire-risk situations while supporting clean installation and professional project acceptance.
NG-A (BTLY) typically refers to a series of mineral-insulated, metal-sheathed (or metal-layer protected) fire-resistant cables for low-voltage systems. Unlike traditional cables that primarily rely on polymer insulation, mineral-insulated cables use inorganic insulation materials as the primary dielectric, combined with a metal protective layer and an optional outer sheath for easy line identification and field handling.
Because naming conventions can vary by region and specification, the procurement of NG-A (BTLY) cables is typically based on project-specified performance requirements (fire rating, smoke protection requirements, wiring type, and acceptance documentation), rather than solely on the name. The correct approach is to match the standards in the Bill of Quantities (BOQ) with the cable's structural and testing requirements.
- Emergency lighting and evacuation route power supply
- Fire pump and sprinkler pump feeders
- Smoke exhaust and stairwell booster fans
- Fire control room power supply and critical monitoring circuits
- Elevator emergency power supply and critical vertical transport circuits
- Hospitals, public places, commercial buildings, and high-occupancy buildings
- Transportation hubs and underground structures with stringent route safety requirements
- Risers, shafts, and service corridors with dense cable routing
- Basements, machine rooms, and utility corridors
- Projects where customers require greater safety than standard PVC/XLPE cables
Mineral insulation is chosen when project design emphasizes the fire resistance of critical circuits and compliance with established acceptance plans.
The combination of inorganic insulation and metallic sheathing ensures reliable performance of fixed wiring in demanding buildings and infrastructures.
NG-A (BTLY) is often chosen when consultants and inspectors focus on the selection, documentation, and delivery consistency of life-safe cables.
The outer sheath is typically used for identification, handling, and line protection (specific selection depends on standards and environment).
- Conductor Preparation: The copper conductor is treated to meet resistance and dimensional targets.
- Mineral Insulation Molding and Compaction: Inorganic mineral insulation material is filled and compacted around the conductor to form the primary insulation system.
- Metallic Protective Layer Molding: A metallic sheath or metallic protective layer is formed around the insulated core, providing sealing and mechanical stability.
- Stabilization and Dimensional Control: The cable is stabilized to ensure dimensional consistency, thereby guaranteeing predictable installation and electrical performance.
- Optional Outer Sheath: A protective sheath can be added to improve handling, abrasion resistance, and line identification.
- Routine Inspections: Typical inspections include conductor resistance, electrical testing according to applicable standards, continuity/structure checks of metal layers, dimensional inspections, and marking verification.

Answer: It is typically used in low-voltage life safety systems, critical service circuits such as emergency lighting, fire pumps, smoke extraction systems, and other lines with explicit fire performance requirements.
Answer: NG-A (BTLY) is widely used in low-voltage systems, typically specified as 0.6/1kV according to project requirements.
A: NG-A (BTLY) is typically used in projects where fire resistance is a priority because its mineral insulation structure uses an inorganic insulation layer and a metallic protective layer, rather than relying primarily on a polymer insulation layer.
A: Many projects require an outer sheath for ease of identification, handling, and abrasion resistance. Specific requirements depend on the wiring environment and acceptance criteria.
A: Mineral-insulated cables typically require compatible termination kits and proper installation techniques to maintain insulation integrity and the continuity of the metallic protective layer. The accessory kit should be compatible with your specified construction and installation method.
