The fusible element of our Type H expulsion fuse links adopts premium silver-copper alloy, manufactured with precision processing and strict testing to ensure highly accurate time-current characteristics, delivering reliable and selective protection for power distribution equipment. The element is crimped to tin-plated copper cables and secured with high-strength stainless steel strain wire, guaranteeing exceptional mechanical strength that remains unaffected by vibration, high current impact and other external factors, eliminating false breaks and ensuring long-term stable operation.
Our fuse links are equipped with a high-performance arc extinguishing tube, delivering excellent arc extinguishing performance even under low current overload faults, rapidly quenching arcs to prevent equipment damage. We also offer Type K and Type T twin pigtails fuse link options, which are far easier to install in fuse cutouts than conventional single pigtail designs, with twin pigtails attaching separately to the attachment studs on each side, reducing installation time and improving maintenance efficiency for on-site teams.
Our 11kV fuse links for expulsion fuse cutout are suitable for matching with expulsion drop-out fuse cutouts in 10-38kV overhead lines, overload and short-circuit protection for distribution transformers and capacitor banks, replacement parts for power grid routine maintenance and emergency repair, matching components for new power distribution equipment manufacturing, rural and urban power grid reconstruction projects, and industrial power distribution system protection. They are the ideal choice for power grid maintenance teams, electrical equipment manufacturers, power system integrators and electrical component distributors.
We provide flexible customization services, including custom rated current specifications from 1A to 200A, fast-acting or slow-blow fuse element options, single or twin pigtails design options, removable or solid buttonhead terminal configurations, and custom length options to fit different voltage grade fuse cutouts. We also offer stable bulk supply services, with sufficient inventory for conventional models, flexible production scheduling for custom orders, and guaranteed lead times to support large-scale project and inventory replenishment needs for commercial and industrial buyers.
All our fuse links for drop-out fuse cutout are manufactured and tested in strict compliance with IEC 60282-2:2008, IEEE Std C37.41-2008 and IEEE Std C37.42-2009 standards. With decades of experience in power protection component manufacturing, we use premium raw materials, implement full-process quality control, and ensure 100% batch testing to guarantee consistent performance. We offer a full range of fuse link types (Type K, Type T, Type H, slow-fast) to meet diverse protection needs, with professional technical support for parameter matching and application guidance, making us your reliable long-term partner for power protection components.
We offer a full current range from 1A to 200A, with standard 11kV models available in all common ratings to meet diverse protection requirements.
