What is BTLY Cable?

BTLY cable, the full name of the isolated (flexible) mineral insulated cable, is a new fire-resistant cable developed based on BTTZ mineral insulated cable.

BTLY Mineral Insulated Cable Model Breakdown

B—-Fixed Installation Power Cable for Wiring
T—-copper conductor
L—-Aluminum sheath special treatment
Y—-Isolation Sleeve

1. The conductor is a circular copper stranded wire (softer compared to the solid copper rod of BTTZ)
2. The insulation layer consists of pure gold mica tape (no longer combined with extruded insulation material, thereby eliminating the generation of carbon particles and improving electrical stability)
3. The metal sheath is a continuously extruded aluminum tube (greatly simplifying the copper tube drawing process for BTT and can replace the grounding wire)
4. Isolation Sleeve (Cross-linked Insulation)
5. Fire-resistant layer
6. Outer sheath plastic (polyolefin Y or polyvinyl chloride V) (optional)

BTLY Cable Production Standards

BTLY cables comply with rigorous international and national standards:

1. BS 6387:1994 Performance Requirements for Circuit Integrity of Cables Under Fire Conditions
2. GB/T 12706.1-2008 “Power Cables with Extruded Insulation for Rated Voltages from 1 kV (Um=1.2 kV) to 35 kV (Um=40.5 kV) and Their Accessories”
3. Comply with the relevant corporate standards

Primary Applications of BTLY Cables

BTLY cables are engineered for critical infrastructure requiring maximum fire safety:
Main power lines, fire protection lines, and emergency evacuation systems, such as emergency lighting, fire monitoring, alarm systems, elevator systems, smoke extraction systems, and control lines.
