Busway systems typically range from 400A to 6300A in capacity and are available in sandwich, air-insulated, or cast resin types. Prices vary significantly based on the conductor material (copper vs. aluminum) and protection ratings, generally ranging from $40 to $1,300 per meter.
1. Sandwich Type Busway (Intensive Type) This is the most common type used in high-rise buildings and industrial plants due to its compact size and excellent heat dissipation.
- Specifications: Common current ratings from 400A to 6300A; usually configured as 4-pole (4P) or 5-pole (5P).
- Pricing: Estimated range of $40–$1,250 per meter (approx. 280–8,950 RMB). Note that copper-core models are significantly more expensive than aluminum ones due to higher conductivity and raw material costs.
2. Шину с воздушной изоляцией These utilize air gaps between the conductors for insulation, making them easier to tap off but bulkier than sandwich types.
- Specifications: Mainstream ratings from 400A to 6300A.
- Pricing: Generally slightly lower than sandwich types for the same amperage, with a standard range of $70–$170 per meter (approx. 500–1,200 RMB).
3. Fire-Resistant & Waterproof Cast Resin Busway Designed for harsh environments or critical safety circuits, these use specialized casting resins for high ingress protection (IP) and fire endurance.
- Specifications: High-durability models ranging from 400A to 6300A.
- Pricing: Due to the specialized manufacturing process, prices range from $115 to $420 per meter (approx. 800–3,000 RMB). High-end models with extreme protection ratings can exceed these prices.
Note: The prices mentioned above are for reference only. Actual project costs depend on specific technical requirements, brand selection, and current market fluctuations in copper and aluminum prices.
