Power Line Fuses

EC Insulator Jiangxi Co., Ltd. is one of the most reliable manufacturers and suppliers of power line fuses in China. With abundant experience, we are committed to offering high quality custom service. Please feel free to wholesale premium power line fuses made in China here from our factory.

If you source protective hardware for overhead power grids, our power line fuses are worth your close look. EC INSULATOR has supplied these reliable power line fuses to utility contractors and distributors across Sri Lanka, Colombia, Venezuela, the United States and South Korea for years. We know grid requirements shift a lot between these markets, so we keep two main build options ready for site selection. These power line fuses work alongside pole mounted transformers and line branches to block damage when overload or short circuit faults pop up out in the field.

Many of our long term buyers mention they value the simple field operation most. Your line crew can swap fuse links without special heavy tools during routine checks or emergency repairs out on the lines. The internal arc suppression setup responds quickly once the fuse element melts, cutting fault current fast and stopping trouble from spreading further along the distribution network.

We build both composite housing units and porcelain housing versions to match different pollution grades and budget plans. Composite style covers rated voltage 15kV, 27kV and 36kV, with continuous current options of 100A or 200A. Breaking capacity hits 10kA for 15kV and 27kV models while the 36kV variant runs at 8kA. Corresponding BIL values sit at 110kV, 150kV and 170kV, with minimum creepage distance ranging from 370mm up to 1080mm and power frequency withstand voltage at 40kV, 45kV and 75kV. Porcelain housing models cover 15kV, 27kV and 38kV, all rated for 100A continuous current. Breaking capacity ranges from 8kA to 12kA. Their BIL ratings span 110kV to 170kV, minimum creepage distance falls between 216mm and 660mm and power frequency withstand voltage reads 40kV, 45kV and 75kV. We also offer F marked composite variants with upgraded arc extinguishing structure for projects that demand stronger fault handling.

We pick raw materials carefully to stand up to harsh outdoor climates. High temperature resistant composite forms the shell for composite types. Fuse elements use high purity conductive metal with steady melting traits. We select internal arc quenching media to deliver reliable arc blowout under rated fault scenarios. All metal fittings go through hot dip galvanizing, which helps fight rust in humid coastal locations our overseas customers often deal with.

We support custom work for bulk orders. You can put your own brand logo printed on the shell or export cartons. Send over your engineering drawing if you need adjusted mounting dimensions. We can also develop non standard current combinations when your project has special technical needs that standard stock cannot cover.

Every batch goes through our in house QC process before shipment. Our staff run visual checks plus sampling performance tests including resistance testing, load simulation and mechanical operation checks. We retain complete test and production records so each shipment stays traceable. We follow IEC standards for production and can share relevant test certificates when you need paperwork for tender submissions.

Our power line fuses are produced following widely accepted IEC standards for distribution equipment. Relevant test reports and certification documents are available upon request for tender review or local authority inspection.

For packing, we pair inner cartons with sturdy export wooden cases to avoid knocks and scratches on the long ocean voyage. If you also buy insulators or transformer accessories from EC INSULATOR, we can combine goods into one container to cut down your total freight cost. We work with FOB and CIF terms as you prefer.,

Our technical team stays available to walk you through installation and product selection questions. Spare fuse links can ship separately for ongoing network maintenance after your project goes live. We reply quickly once you send us technical questions after receiving cargo.

These units fit overhead distribution circuits, pole mounted transformers, rural grid renovation and urban secondary distribution networks. A large share of our customers in Sri Lanka, Colombia and Venezuela order them for outdoor grid upgrade jobs.
