Installation cable HDHP-J 750V 3x2.5 (B2CA) HDHP-J7-3X2,5(B2CA)

Installation cable for safe installations

HDHp-J 3x2.5 is a reliable solution for electrical installations where high fire resistance and limited emission of toxic substances are required. This flat cable features three copper conductors designed for operation at 750V. Its halogen-free construction ensures safety during fire events by minimizing the risk of toxic gas and smoke generation.

Construction and application

This cable features a flat design, facilitating installation in confined spaces—under plaster, within walls, or beneath flooring. The solid-core copper conductors (Class 1) ensure excellent conductivity and flexibility. Both insulation and outer sheath are made from halogen-free polymers compliant with class B2ca, indicating limited flammability and low smoke emission. As a result, the HDHp-J cable is ideal for use in public buildings, religious facilities, hospitals, schools, and any location where fire safety is critical.

Key features and benefits

• Halogen-free: Reduces the risk of toxic gas generation during fire, protecting users’ health and lives.
• Fire reaction class B2ca: Meets stringent fire safety standards, ensuring a high level of installation safety.
• Flat design: Simplifies routing and installation in tight spaces.
• Solid-core copper conductors: Provide excellent electrical conductivity and flexibility during installation.
• Wide operating temperature range: Reliable performance from -40°C to +70°C under varying environmental conditions.
• Mechanical damage resistance: Robust outer sheath protects the cable from damage during installation and operation.
• Suitable for buildings with enhanced requirements: Perfect for installations in public buildings, hospitals, schools, and other facilities with high fire safety standards.
