Sandwich Type Air Insulated Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. develops and produces sandwich type air insulated busway, which is widely adopted in commercial towers, underground utility tunnels, compact power rooms and high-rise building electrical shafts. Different from conventional separated air insulated busway, this sandwich type air insulated busway arranges conductors in compact laminated sandwich structure. The optimized phase spacing reduces overall volume greatly while keeping excellent air insulation performance. It can bear strong short-circuit impact, realize stable power transmission, and is an ideal choice for projects with narrow installation space and strict layout requirements.

Product Parameter (Specification)

Product Features and Application Scope

The sandwich type air insulated busway is tailor-made for space-constrained power distribution engineering. Its compact sandwich laminated structure shrinks the overall profile without sacrificing electrical performance. The product boasts strong short-circuit withstand capability, stable temperature rise and good vibration resistance. It solves the bottleneck that ordinary busway is too large to install in narrow shafts.

Core Advantages

1. Compact Sandwich Laminated Structure, Space-saving Conductors are stacked in sandwich layout, greatly reducing overall width and height. It fits perfectly into narrow cable shafts and compact power rooms, maximizing space utilization.

2. Superior Short-circuit Withstand Capacity The laminated sandwich structure provides mutual supporting effect between conductors. It can resist huge electrodynamic force during short-circuit accident, avoiding deformation and damage of busbar.

3. Stable Air Insulation & Low Temperature Rise Reasonable air clearance between layers ensures reliable air insulation. Natural air convection brings good heat dissipation, keeps low temperature rise under rated load and reduces long-term energy consumption.

4. Lightweight & High Rigidity Shell High-strength aluminum alloy enclosure features light weight and high rigidity, anti-corrosion and anti-impact, adapting to long-term operation in basement and high-rise shaft environment.

5. Convenient Branch Tap-off & Flexible Layout Modular design supports quick tap-off box installation. Branch outlets can be reserved at any position along the busway, convenient for later power expansion and renovation.

6. Factory Direct Supply & Engineering Customization Qingdao Fenghua Electric supplies sandwich type air insulated busway directly from factory. We customize dimensions, tap-off positions and protection grades to match compact building projects.

Application Scenarios High-rise residential & commercial buildings, underground comprehensive pipe gallery, compact power distribution room, hospital and school electrical shaft, shopping mall trunk power supply, old building power renovation with narrow installation space.

Production Details and Craftsmanship

Qingdao Fenghua Electric strictly controls the whole production process of sandwich type air insulated busway. The core conductors are precisely cut and surface treated, neatly stacked into sandwich laminated structure with uniform reserved air gaps. The positioning insulation spacer fixes each conductor layer steadily to prevent displacement under electromagnetic force. The shell adopts one-piece extrusion molding, tight assembly and good dustproof performance. Each finished busway will pass insulation test, power frequency withstand voltage test and short-circuit simulation inspection before delivery. We support sample inspection, non-standard customization and bulk tender procurement for global engineering buyers.
