Cast Resin Busbar Trunking System in Bangladesh

Power distribution environment is not the same everywhere. A cast resin busbar trunking system is a suitable & reliable solution for the places where fire risk, moisture, dust, or outdoor exposure are given major concerns. Conventional busbar or cable systems aren’t the right one.

Edison Power supplies cast resin power bar systems in Bangladesh for industrial facilities, substations, and infrastructure projects where safety, environmental resistance, and long-term reliability are critical.

Why Cast Resin Busbar Is Used

The key difference with a cast resin busbar system lies in its construction. The conductors are fully encapsulated in high-grade epoxy resin, creating a sealed and solid insulation barrier.

This design provides:

• Advanced protection against fire and overheating
• Resistance to moisture, dust, and chemicals
• Stable performance in outdoor and harsh environments
• Minimal maintenance over long operating periods

Cast resin busbars are often considered as fire-resistant busbar systems in safety-critical installations for these characteristics.

What Is a Cast Resin Power Bar?

A cast resin power bar is a prefabricated busbar trunking system where copper or aluminium conductors are permanently enclosed within epoxy resin insulation and protected by a robust outer housing.

Cast resin busbars do not rely only on air or surface insulation like the other standard enclosed busbars. This makes them suitable for environments where traditional busbar systems would require additional protection or enclosure upgrades.

Typical Applications

Based on practical project experience, cast resin busbar systems are widely used in:

• Chemical and pharmaceutical plants
• Power plants and substations
• Outdoor electrical installations
• Basements and underground facilities
• High-humidity or coastal environments
• Industrial zones with elevated fire risk

In these locations, system reliability and safety take priority over compactness or cost.

Fire Safety and Environmental Protection

Cast resin busbar systems are designed to minimize fire hazards. The epoxy insulation is self-extinguishing and does not support flame propagation. Since the system is oil-free, there is no risk of leakage or combustion associated with liquid insulation.

Additional advantages include:

• Low smoke emission
• No toxic gas release during faults
• Easier approval from fire safety authorities

These features make cast resin busbars particularly suitable for modern industrial buildings and regulated environments.

Outdoor Performance and IP Protection

Cast resin busbar systems are often specified as outdoor busbar solutions because they can achieve high ingress protection levels, including IP68 in certain configurations.

This allows the system to operate reliably in:

• Rain-exposed areas
• Dust-heavy industrial zones
• Temperature-variable environments

Where conventional busbar systems would need secondary protection, cast resin systems provide built-in environmental resistance.

Installation and Technical Support in Bangladesh

Frequently Asked Questions

Q. Is a cast resin busbar completely fireproof?

A: No electrical system is completely fireproof. Cast resin busbars are fire-retardant and self-extinguishing. It reduces fire risk significantly compared to the other conventional solutions.

Q. Can cast resin busbars be installed outdoors?

A: Yes. Cast resin busbars can be installed outdoors due to their high ingress protection and sealed insulation.

Q. Do cast resin systems offer copper and aluminium options?

A: Yes. Cast resin busbar systems are available with both copper and aluminium conductors, depending on load and project requirements.

Q. Do cast resin busbars require frequent maintenance?

A: No. When properly installed, maintenance requirements are minimal.

Q. Does Edison Power provide installation services?

A: Yes. Edison Power supplies, installs, and supports cast resin busbar trunking systems throughout Bangladesh.
