BTWGT 300/500V Flexible Mineral-Insulated Fire-Resistant Cable

BTWGT Cable Advantages 
Flat Structure Optimized for Travel: Flat design reduces the space occupied in the elevator shaft, suitable for installation in limited spaces  
Long Bending Lifespan: Specifically designed for repeated winding and bending environments, extending elevator service cycles  
Multi-Core Integration with Full Functionality: Integrates power, control, communication, and video cores, simplifying wiring complexity  
Good Anti-Interference Capability: Special structure reduces interference between internal cores, ensuring stable signal transmission  
Easy Installation and Maintenance: Integrated flat design facilitates installation and later maintenance  

BTWGT Cable Selling Points  
Specialized Flat Cable for Elevator Travel: Specifically designed for elevator hoistway travel cable scenarios, replacing traditional round cable solutions  
Integrated Multi-System Solution: A single cable integrates power, control, and communication needs, reducing wiring costs  
Reliable for Dynamic Use: Passes repeated bending tests, meeting long-term operational reliability requirements for elevators  
Saves Shaft Space: Flat structure reduces space occupation in the elevator shaft, optimizing elevator design  
Flexible Specification Adaptation: Supports customization of core count and length based on elevator load capacity, speed, and floor height  

BTWGT Cable Application Scope  
Elevator Travel Cable Systems: Travel wiring for various passenger elevators, freight elevators, and medical elevators  
Elevator Control and Communication: Transmission of control signals, video monitoring, and intercom communication between the car and control cabinet  
Internal Wiring for Escalators: Connection cables between escalator drives and control units  
Lifting Systems for Automated Parking Garages: Power and control transmission for hoist travel in shuttle-type parking garages  
Special Lifting Equipment: Travel power and control wiring for construction hoists, stage lifts, and other equipment  
Compliance Certifications: CCC (for some models), CE (optional), compliant with GB/T 5023 and elevator industry standards

Parameter Category | Speculative/Typical Specification  
Conductor | Annealed copper conductor.  
Insulation | Possibly cross-linked polyethylene (XLPE) or mineral composite tape (mica tape).  
Key Structure (WG) | Oxygen barrier/flame retardant layer: Located between the insulation and outer sheath, consisting of metal hydrate, ceramicized silicone rubber, or other highly efficient oxygen barrier and intumescent flame retardant materials. Forms a hard, carbonized insulating layer in case of fire.  
Sheath | Halogen-free, low-smoke, flame-retardant polyolefin.  
Rated Voltage | 0.6/1kV.  
Fire Performance (Core) | Possibly claims compliance with:  
• Flame retardance: Class A bunched cable burning (IEC 60332-3C).  
• Fire resistance: Meets specific classifications of GB/T 19216 or BS 6387 (e.g., CWZ, 950°C/3h).  
• Halogen-free, low smoke: Complies with IEC 60754 and 61034.  
Long-term Operating Temperature | 90°C (XLPE insulation) or 70°C.  
Installation Characteristics | Good flexibility, installation similar to ordinary power cables, simpler than mineral-insulated cables.
