XRNP1 Series High Voltage Current Limiting Fuse is a professional special protection fuse tailor-made for high-voltage voltage transformers and instrument transformer supporting systems. It covers complete mainstream rated voltage specifications: 10kV, 24kV, 35kV, with matched complete ampere ratings including 0.5A, 1A, 2A, 3.15A, 5A. It is the standard matching core component widely used in indoor medium and high voltage switch cabinets, PT cabinets, complete power distribution control equipment, and supporting protection of substation precision instrument transformers, fully adapting to all conventional power engineering supporting scenarios of global high-voltage power distribution systems.
This XRNP1 transformer protection fuse adopts high-purity special melt body and high-density quartz sand arc-extinguishing filling material, matched with integrated high-strength insulation ceramic tube closed structure. It has ultra-sensitive fusing characteristics, precise current limiting control performance and excellent high breaking capacity. It can quickly and accurately cut off instantaneous overload current and short-circuit sudden faults in the circuit, effectively isolate faulty transformer equipment, avoid precision instrument transformer burnout, insulation breakdown and power system secondary loop failure risks. The whole product is resistant to high temperature, moisture, aging and internal partial discharge, runs stably for a long time in closed indoor high-voltage cabinet environments, with low failure rate and no daily complex maintenance, greatly reducing later engineering operation and maintenance costs.
We are a professional certified Chinese direct manufacturer focusing on medium and high voltage instrument supporting fuses for more than 20 years. All XRNP1 series transformer protection fuses are produced in strict accordance with unified IEC international electrical standards and national industry specifications, with unified standard overall dimensions, strong universal interchangeability, no installation and matching obstacles for global mainstream complete switchgear. We fully support non-standard ampere values, special overall length, customized installation terminals and engineering special parameter processing according to customer site drawing requirements.
