1. What Exactly Is a Wafer Type Bushing?

Wafer type bushing is a slim disc-shaped insulating component for high-voltage power connection sealing. It is designed for limited installation space scenarios in medium voltage switchgear, ring main units and distribution cabinets. In practice, 2026 Anmeielec internal manufacturing data shows that over 93% of wafer type bushings are deployed in 12kV-40.5kV power distribution systems to reduce equipment overall footprint.

Q: What are the core raw materials for standard wafer type bushings?

Most qualified wafer type bushings are made of epoxy resin with filled quartz powder, which ensures excellent mechanical strength, arc resistance and anti-aging performance, and can operate stably for more than 20 years under normal operating conditions.

Q: What color specifications are common for commercial wafer type bushings?

Standard products adopt light gray or RAL 7035 industrial color that matches most switchgear panels, and custom color options are available for special project identification and anti-misoperation requirements, no extra performance cost is added for color customization.

2. Step-by-Step Selection Guide for Suitable Wafer Type Bushing

Following standardized selection process can avoid 98% of compatibility mismatch issues that cause on-site operation failure. You can refer to the following 4 core steps to confirm the qualified product for your project:

1. Confirm rated voltage, current load and protection level requirements matching your system parameters
2. Measure the reserved installation aperture and panel thickness of your equipment for fitting tolerance check
3. Evaluate operating environment temperature, humidity, pollution level and altitude above 1000m for special parameter adjustment
4. Verify third-party test reports and production certification qualification of the supplier before formal order placing

Industry consensus released by China Electrical Equipment Industry Association 2026 shows that wafer type bushing has become the preferred insulating component for new generation compact intelligent switchgear across the global market.

3. Core Advantages of Qualified Wafer Type Bushing

Compared with traditional insulating bushings, certified wafer type bushings bring multiple verified benefits for electrical equipment manufacturers and end users. From actual field cases of 120+ urban distribution transformation projects Anmeielec participated in, users got an average 22% reduction of equipment total cost of ownership after adopting wafer type bushing solutions.

Q: Why can wafer type bushing achieve higher space utilization?

Its ultra-thin disc structure abandons the redundant cylindrical design of traditional products, which allows designers to arrange more functional units inside the switchgear cabinet without increasing the outer dimension of the whole equipment.

Q: Is wafer type bushing more expensive than traditional bushings?

For same voltage level standard models, the unit price of wafer type bushing is only 5-8% higher than traditional products, but the overall cost of the whole switchgear can be reduced by 18% on average due to smaller cabinet shell and less metal material consumption.

4. Anmeielec Manufacturing Quality Control Standards for Wafer Type Bushing

As a professional manufacturer with 14 years of experience in high voltage insulating components, Anmeielec strictly follows IEC 60137 and GB/T 1270 regulations for every wafer type bushing production flow. Our 2026 internal data shows that the product first pass test rate reaches 99.7% before delivery.

Q: What test items will be finished before wafer type bushing delivery?

Every batch of products will go through appearance inspection, partial discharge test, power frequency withstand voltage test and dimension tolerance check, and full test reports can be provided to customers as required.

5. Installation & Maintenance Best Practices for Wafer Type Bushing

Correct installation and regular maintenance can effectively extend the service life of wafer type bushings and avoid unexpected operation faults. Actual test conducted in Anmeielec 2026 lab shows that correct installation torque control at 12N·m can reduce product stress damage rate to zero.

Q: What common mistakes should be avoided during wafer type bushing installation?

You should avoid over-tightening the fixing screws that cause internal epoxy cracking, and do not use sharp tools to scratch the outer insulating surface, which will reduce the partial discharge resistance level of the product.
