Technical Specifications

Models and Options

BTTZ is one of the mineral insulated cable models offered. Other models include BTTRZ and BTLY, each designed for specific requirements such as flexibility and higher temperature ratings.

Materials and Structure

The cable uses mineral insulation, which provides high temperature resistance and fire safety. The conductor is typically copper, ensuring excellent conductivity.

Applications

• Emergency fire systems (fire pumps, smoke extraction fans, exit lighting)
• High-temperature industrial zones (furnaces, glass melting, steel casting)
• Critical infrastructure (nuclear power plant control rooms, hospital operating theaters)
• Explosive atmospheres (hazardous chemical storage areas)

Customization

Shenghua Cable offers customized solutions for special project requirements, including voltage, conductor size, and sheath material.

Case Study

In a medium-scale industrial system integration project in Great Britain, BTTZ cables were installed for industrial monitoring systems. Over 15 years, the cables maintained system stability and safety, even in harsh environments, supporting high-precision data acquisition and predictive maintenance.
