Polymer insulated self-dropping fuse

Outdoor drop-in fuses are designed for medium-voltage power grids from 12kV to 40.5kV. They protect transmission lines and distribution substations against overload and short circuits, as well as disconnecting equipment. Designed and manufactured by Vina Electric Joint Stock Company, these drop-in fuses are highly durable, made with advanced technology, robust, precise, and convenient for transportation, installation, operation, and maintenance. The main materials are hot-dip galvanized steel, stainless steel, polymer insulation, and standard silver-plated copper contacts. Vina Electric's drop-in fuses are designed for medium-voltage power grids from 12kV to 40.5kV, used to protect transmission lines and distribution substations against overload and short circuits, as well as disconnecting equipment. – Applicable standards: TCVN, IEC282-2 and ANSI/IEEE37.41. – Rated voltage: 12/24/33/40.5kV – Rated current: 100A 200A – Rated frequency: 50Hz – Short-circuit breaking capacity: 12kA – Insulation material: Polymer porcelain insulator – The FCO outdoor series is developed based on the most common conditions and applications. Typical equipment samples have been tested in the laboratories of the Quatest 1, Quatest 2, and Quatest 3 quality measurement centers and general departments. All metal parts undergo special treatment processes to prevent erosion and rust. The Vina Electric FCO-VN type self-dropping fuse is composed of the following main parts: – Silicone insulating support with a large leakage current length. – Upper and lower contact assemblies made of electrical copper. – Reasonable fuse wire structure, easy to disassemble and replace. – Lightweight, easy to transport and install. – High durability suitable for tropical environments, industrial dust, coastal areas, salt spray, etc. 27kV Self-Dropping Fuse – 200A
