EC Insulator Jiangxi Co., Ltd. is one of the most reliable manufacturers and suppliers of 100a porcelain fuse cutout in China. With abundant experience, we are committed to offering high quality custom service. Please feel free to wholesale premium 100a porcelain fuse cutout made in China here from our factory.
Product Overview
Our 100A porcelain fuse cutout is an outdoor high voltage dropout fuse, widely deployed on overhead distribution power lines. This 100A porcelain fuse cutout adopts glazed porcelain housing and pole-mounted installation, to safeguard pole transformers and overhead lines against overload and short circuit faults.
When fault current melts the internal fuse link, the fuse tube drops down automatically. It offers field crews a clear visual fault signal, helping them quickly find the fault spot and complete on-site maintenance. Power utilities across many regions choose our 100A porcelain fuse cutout for reliable overhead line protection.
Application Range
We have supplied this RW series fuse cutout for many years for pole transformers and overhead distribution networks. It works reliably in harsh outdoor conditions, including coastal sites with salt fog and industrial areas with heavy pollution.
Our clients deploy this unit in rural grid renovation, mine power distribution, and small solar branch circuits. The glazed porcelain shell keeps insulation stable even when temperatures swing a lot between day and night.
Product Features
This 100A cutout works on a simple gravity dropout principle. Once the fuse element blows under fault conditions, the tube drops reliably to isolate the circuit safely.
The glazed porcelain body is designed with proper creepage distance. We match different models to suit various voltage classes. All metal fittings are hot-dip galvanized, to resist rust after years of outdoor exposure. The whole assembly can withstand wind vibration, a common scenario for pole mounted equipment.
Material Advantage
We make the housing from high-alumina porcelain fired under high temperature. This material delivers strong mechanical strength and good anti-tracking performance. The fuse tube is filled with arc-extinguishing medium, which can put out electric arcs fast once the fuse trips under fault current.
All metal hardware goes through hot-dip galvanizing treatment. It protects parts against corrosion in humid or polluted outdoor locations. We inspect every batch of raw porcelain blanks before glazing and assembly, to keep quality steady batch by batch.
Quality Control
Every finished cutout will go through our in-house factory tests before shipment. The in-house tests include dimension check, power frequency withstand voltage test and mechanical operation test.
Apart from these routine outgoing tests, official type test reports can be provided upon client request. We keep batch test records for review, covering all electrical and mechanical parameters. Any non-conforming units will be reworked or discarded; we never arrange shipment for defective goods.

Note: RW-27/100-8 has two versions with different BIL and creepage values for different project specifications. Custom design and production are available to meet your special project requirements.
Custom Support
We can adjust mounting brackets according to your site drawings if your project has special requirements. We also supply matching fuse links to meet your target breaking current requirement. Export plywood packaging and product marking details can be adjusted as you need.
For bulk orders, production normally takes 25-35 days after receiving your deposit. The actual lead time will change with order quantity and our component stock status. We use reinforced plywood cases for sea transport, to protect the cutouts and avoid damage during long ocean shipping. We can print your brand logo or project code on porcelain body and metal parts as requested.
