Jinhua Dika Electrical Equipment Co., Ltd., a reputable ISO9001-certified manufacturer based in Zhejiang, China, specializes in delivering robust high-voltage solutions for global power infrastructure. With over US$1 Million in annual exports reaching diverse markets from North America to Oceania, we present our 100A/200A High Voltage Fuse Switch integrated with Zinc Oxide Arrester for 33kV/35kV systems. This engineered solution combines critical circuit protection and overvoltage suppression in a single, reliable unit, designed to enhance grid stability and reduce equipment downtime. Engineered for harsh environments, it offers utilities and industrial users a cost-effective safeguard against electrical faults and transient surges.

Core Product Features & Technical Advantages:

Dual-Function Design: Integrates a high-voltage fuse switch for safe load breaking/isolation and a Zinc Oxide (ZnO) arrester for superior surge protection, eliminating the need for separate devices and saving installation space.
Advanced Arrester Technology: Utilizes highly nonlinear Zinc Oxide varistors, providing rapid response to voltage surges (lightning, switching transients) with excellent energy absorption capacity and stable protection levels.
Robust Construction: Features high-quality porcelain or polymer insulators offering exceptional mechanical strength, pollution resistance, and long-term dielectric stability for outdoor applications.
Safe & Reliable Operation: Clear visible break indication and secure earthing provisions ensure operator safety during maintenance. The fuse provides reliable short-circuit protection for downstream equipment.
Wide Compatibility: Suitable for use in air-insulated switchgear (AIS), pole-mounted transformers, capacitor banks, and cable feeders within 33kV/35kV distribution networks.

Key Technical Specifications:

Parameter	Value
Rated Voltage (Ur)	33kV, 35kV
Rated Current (Ir)	100A, 200A (Standard)
Rated Short-Time Withstand Current (Icw)	Typically 20kA / 3s (Customizable)
Rated Breaking Current (Fuse Dependent)	Up to System Fault Level
Arrester Type	Zinc Oxide (ZnO) without gaps
Rated Arrester Voltage	Appropriate for 33kV/35kV systems
Insulation Level	Standard: 70kV Power Frequency / 170kV Lightning Impulse
Mechanical Life	≥ 2000 Operations
Ambient Temperature	-25°C to +55°C
Installation	Vertical or Horizontal (Pole/Structure)

Benefits for Your Operations:

Enhanced System Protection: Comprehensive defense against both overload/short-circuit currents (fuse) and destructive voltage surges (arrester), minimizing equipment damage and costly outages.
Reduced Maintenance & Costs: The integrated design simplifies installation, reduces points of failure, and lowers overall system maintenance requirements compared to separate components.
Improved Grid Reliability: Minimizes unexpected disconnections and protects sensitive downstream equipment, contributing to higher network availability and power quality.
Operational Safety: Clear isolation point and earthing capabilities ensure safe working conditions for personnel during switching or fuse replacement.
Global Compliance & Flexibility: Manufactured under ISO9001 quality management, with design adaptability to meet specific regional standards or project requirements upon request.

Frequently Asked Questions (FAQ):

Q: Is this unit suitable for both transformer and feeder protection?
A: Yes, the combined fuse switch and arrester is ideal for protecting distribution transformers, capacitor banks, and cable feeders in 33kV/35kV networks against overcurrents and overvoltages.
Q: Can the fuse be easily replaced after operation?
A: Absolutely. The design typically allows for safe and straightforward replacement of the fuse link without requiring specialized tools, minimizing downtime.
Q: Why is the Zinc Oxide arrester integrated?
A: Integrating the ZnO arrester provides essential protection against transient overvoltages (like lightning strikes) directly at the switch point, safeguarding the switch itself and downstream equipment, which a fuse alone cannot do.
Q: What are the mounting options available?
A: The switch is designed for versatile mounting, commonly used on poles (pole-top) or structures within substations. Specific mounting brackets can be discussed based on your application.
Q: Do you offer different fuse characteristics (e.g., K, T, slow/fast blow)?
A: Yes, fuse characteristics can be selected (e.g., back-up type) to match the specific protection coordination requirements of your system. Please specify your needs when inquiring.
Q: Is the switch suitable for frequent load breaking operations?
A: While primarily designed for isolation and fault protection, the load break switch mechanism allows for reliable manual switching of load currents within its rated capacity. It is not intended for very high-frequency switching like a contactor.
Q: What is the expected lifespan of the Zinc Oxide arrester?
A: ZnO arresters have a long service life under normal operating conditions. Their condition can be monitored via leakage current measurement, and they are designed for years of reliable service without maintenance.
Q: Can you provide specific test reports (e.g., type test)?
A> Test reports (such as power frequency withstand, impulse withstand, temperature rise) are available upon request. We ensure our products meet relevant industry standards.
