Air Insulated Busway for Substation

Qingdao Fenghua Electric Manufacturing Co., Ltd. develops Air Insulated Busway for Substation, specially engineered for power station and substation interconnection scenarios. Unlike conventional building busways, substation busway bears huge short-circuit electrodynamic force and high instantaneous thermal load during grid faults. It serves as the critical link connecting the low-voltage outlet of distribution transformers to switch cabinets. Adopting reinforced air insulation framework and heavy-duty conductor design, it maintains stable electrical performance under large current impact, vibration and temperature cycling. It is widely adopted in box substations, indoor power substations and prefabricated substation renovation projects, ensuring safe and reliable power transfer from transformer to distribution switchgear.

Product Parameter (Specification)

Product Features and Application Scope

This air insulated busway is tailor-made for substation power interconnection. Core design focuses on high short-circuit withstand capacity, strong thermal stability and mechanical rigidity, to resist severe dynamic and thermal impact under short-circuit faults, which is the key difference compared with ordinary building busway.

Core Advantages

1. High Short-circuit & Thermal Stability Heavy-duty conductor and reinforced support structure can withstand large peak current and thermal energy during short-circuit accidents, preventing permanent deformation and burnout of the bus system.

2. Heavy-duty Mechanical Structure & Vibration Resistance Rigid frame and fixed insulating spacers resist vibration from transformer operation and short-circuit electromagnetic force. Phase spacing remains unchanged under impact.

3. Reliable Air Insulation under Temperature Cycling Scientific air gap design adapts to large temperature fluctuation inside substation room. Insulation performance stays stable under repeated heating and cooling cycles.

4. Precise Docking with Switchgear & Transformer Customizable length and terminal connection interface match transformer low-voltage terminals and switch cabinet inlet, simplifying on-site alignment and installation work.

5. Dust & Moisture Resistant for Substation Room Tight enclosure structure reduces dust and moisture ingress, suitable for semi-enclosed substation chambers and box-type substation environments.

6. Power Engineering Customization & Witness Test Qingdao Fenghua Electric can optimize cross-section, terminal structure and protection grade according to substation single-line diagram and power engineering requirements.

Application Scenarios Box-type substation transformer low-voltage connection, indoor distribution substation, prefabricated modular substation, power station auxiliary power distribution, substation capacity expansion and renovation projects.

Production Details and Craftsmanship

Qingdao Fenghua Electric implements power-industry production standards for Air Insulated Busway for Substation. Conductors adopt thickened cross-section and surface anti-oxidation treatment to reduce contact resistance. High-strength flame-retardant insulating supports lock phase air gaps firmly to resist electromagnetic impact. The enclosure uses thick alloy plate for higher rigidity. Every finished section goes through insulation resistance test, power frequency withstand voltage test, temperature rise test and short-circuit withstand verification before delivery. We support power project witness inspection, non-standard terminal customization and bulk tender supply for power EPC contractors.
