Product Overview

The RN1 series high voltage fuse is a professional current-limiting protective component designed for medium-voltage power systems (3.6kV-35kV). It is mainly used for short-circuit and overload protection of power transformers, high-voltage switchgear, power distribution cabinets, and other key power equipment. With its excellent current-limiting performance and precise fusing characteristics, it can quickly cut off fault currents in milliseconds, effectively preventing equipment damage and power grid failures, thus safeguarding the safe and continuous operation of the entire power distribution system. It is widely applied in industrial power plants, power distribution substations, commercial buildings, and other high-voltage power supply scenarios.

Core Features

Excellent Current-Limiting Performance: Adopts advanced current-limiting structure, which can quickly limit the fault current to a safe range before the peak value, minimizing the impact of short-circuit current on power equipment and power grids, and reducing maintenance costs.
High-Precision Fusing Characteristics: Equipped with a high-sensitivity melt, calibrated strictly according to the operating parameters of medium-voltage equipment, ensuring accurate response to overload and short-circuit faults without misoperation under normal working conditions. The fusing characteristic error is less than ±10% for reliable protection.
Durable Ceramic Structure: The outer tube is made of high-strength alumina ceramic, which has excellent high-temperature resistance, pressure resistance, and insulation performance. It can withstand the high temperature and pressure generated during arc extinction, ensuring long service life and stable performance in harsh working environments.
Safe & Reliable Arc Extinction: Filled with high-purity quartz sand as the arc-extinguishing medium, which can quickly absorb arc energy, cool and extinguish the arc in a short time, preventing arc reburning and ensuring safe disconnection of fault circuits. The sealed structure avoids arc leakage and improves operational safety.
Easy Installation & Wide Compatibility: Designed for indoor cabinet installation, with compact structure and standardized size, suitable for most medium-voltage switchgear and power distribution cabinets. Factory-calibrated, no additional adjustment is required during installation, and replacement is convenient. It supports a full range of specifications to meet different power system requirements.

Application Scenarios

The RN1 high voltage fuse is widely used in medium-voltage power systems (3.6kV-35kV), mainly applicable to:

Short-circuit and overload protection of power transformers, high-voltage switchgear, and power distribution cabinets in industrial and commercial power supply systems.
Protection of medium-voltage power lines, transformers, and electrical equipment in power distribution substations and industrial power plants.
12kV, 24kV, 35kV power grid distribution systems, especially suitable for scenarios requiring high-precision current-limiting protection.
Indoor power distribution scenarios such as commercial buildings, industrial workshops, and high-rise residential areas, where stable and reliable power protection is required.
Protection of auxiliary equipment in power systems, such as voltage transformers and current transformers, to prevent fault expansion.
