Installation Instructions for High-Temperature Resistant Busbars

High-temperature resistant busbars must be handled, stored, and installed carefully using proper lifting, insulation, and assembly techniques to ensure safety and optimal performance.

Handling and Storage

Transport and Unloading: Use forklifts or cranes to move busbar modules safely. Insert metal rods through designated lifting holes or use lifting straps/slings to maintain balance. Avoid dragging busbars on the floor or using steel ropes/hooks that may damage the modules ( ).

Storage Conditions: Store busbars in a dry, clean, and covered environment. Resin and hardener materials should be kept between 5°C and 25°C and protected from direct sunlight. Use wooden spacers every 1.

5 m between layers and avoid stacking more than five modules horizontally ( ). Protection from Liquids: Busbars must not come into contact with water or other liquids before assembly, as incomplete assembly leaves them unprotected ( ).

Installation Procedures

Positioning: Mount busbars on longitudinal stays or supports according to the system design. Standard spacing is typically 60 mm, but 40 mm, 100 mm, or 185 mm may be used depending on the application ( ). Temperature Considerations: Ensure the busbar temperature does not exceed the rated limits, which depend on current, cross-section, surface, and ambient conditions.

Centralized infeed and symmetrical load distribution optimize thermal performance ( ). Assembly: Avoid torsion, dents, or sharp impacts. Flexible busbars may require hot pressing or bonding with ceramic or silicone insulation tapes to maintain high-temperature performance ( ).

Rigid busbars are suitable for high-current main lines, while flexible busbars are ideal for confined spaces ( ). Insulation: Use high-temperature resistant materials such as mica, ceramic, or silicone rubber tapes for insulation. Factory-installed flame-retardant wraps, like polypropylene, can prevent arc propagation and improve safety ( ).

Connection to Devices: Busbars can be used to mount protective devices such as circuit breakers or fuse switch disconnectors. Ensure short-circuit strength is compatible with the prospective current at the installation site ( ).

Safety Precautions

Only qualified personnel should handle and install busbars, using rubber gloves, helmets, safety glasses, face shields, and flame-resistant clothing ( ). Follow all manufacturer instructions and IEC standards (e.g., IEC 61439-6) to prevent personal injury, equipment damage, or fire hazards ( ). Inspect all components for transit damage and verify quantities against the packing list before installation ( ).

Maintenance and Operation

Ensure busbars remain free from dust, mud, or corrosive materials. Regularly check insulation integrity and connections to maintain electrical performance and prevent overheating ( ). Avoid exceeding rated current and temperature limits to ensure long-term reliability ( ).

By following these handling, storage, installation, and safety guidelines, high-temperature resistant busbars can operate reliably in demanding industrial environments while minimizing risks to personnel and equipment.
