As a specialized manufacturer in the electrical equipment industry, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our robust High Voltage Disconnector with Epoxy Resin Insulator. Engineered for reliability and safety in demanding power distribution environments, this disconnector is a critical component for system isolation and maintenance. With a solid foundation backed by comprehensive quality management systems including ISO9001, our product is designed to meet the rigorous demands of global markets from North America to Southeast Asia, ensuring operational continuity and personnel safety.
This disconnector is engineered to provide a visible break in high voltage circuits, facilitating safe maintenance and system reconfiguration. Its core construction utilizes a high-grade epoxy resin insulator, known for excellent dielectric strength, tracking resistance, and durability against environmental stressors like moisture, UV radiation, and pollution. The unit is rated for 36kV and 630A, making it suitable for a wide range of substation and feeder applications.
- Superior Insulation Performance: The epoxy resin insulator offers high mechanical strength and exceptional electrical insulation, reducing the risk of flashover and ensuring long-term reliability even in harsh conditions.
- Robust Mechanical Design: Constructed with high-strength materials, the operating mechanism ensures smooth, reliable switching operations for thousands of cycles, with a mechanical life exceeding 3000 operations.
- Enhanced Safety Features: Provides a clear, visible air gap when in the open position, a fundamental safety requirement for personnel working on de-energized lines. Optional earthing blades can be integrated for additional safety during maintenance.
- Corrosion and Weather Resistance: Critical metallic components are treated with advanced anti-corrosion coatings, while the epoxy resin is inherently resistant to weathering, ensuring consistent performance in coastal or industrial atmospheres.
- Flexible Operation Options: Available with manual operation via an insulated pole or can be equipped with a motorized drive for remote operation, supporting the automation of distribution networks.
- Easy Installation and Maintenance: Designed for straightforward mounting on structures or in switchgear assemblies. The minimal maintenance requirements translate to lower lifecycle costs.

Frequently Asked Questions (FAQ):
Q1: What is the primary advantage of using an epoxy resin insulator over a porcelain one?
A: Epoxy resin insulators offer superior resistance to impact damage, have better pollution and tracking resistance, and are generally lighter in weight, making installation and handling easier and safer.
Q2: Can this disconnector be used for load breaking, or is it only for isolation?
A: This unit is primarily designed as an isolator to provide a visible break for safety. For making and breaking load currents, a dedicated load break switch would be recommended. However, some designs may incorporate limited load-breaking capability; please consult our technical team for your specific application.
Q3: Is a motorized operating mechanism available?
A: Yes, a motorized drive is available as an optional feature. This allows for remote operation and integration into SCADA systems, which is beneficial for automated or unmanned substations.
Q4: What are the standard mounting arrangements?
A: The disconnector is designed for flexible mounting. It can be installed in either a vertical or horizontal orientation on steel structures, depending on the layout of your switchyard or switchgear.
Q5: What international standards does this product comply with?
A: The disconnector is designed and tested in accordance with prevalent international standards such as IEC 62271-1 and IEC 62271-102. Compliance with specific regional standards like ANSI can be addressed based on customer requirements.
Q6: What is the expected service life of the epoxy resin insulator?
A: Under normal operating conditions within the specified ambient temperature range, the epoxy resin insulator is designed for a long service life, typically exceeding 20 years, thanks to its excellent weathering and electrical aging properties.
Q7: Do you provide earthing (grounding) blades with the disconnector?
A: Earthing blades can be supplied as an integrated option or as a separate assembly. This feature is crucial for safely earthing isolated sections of the line during maintenance.
Q8: What is the lead time for an order, and what are the main shipping ports?
A: Lead times vary based on order quantity and configuration (manual vs. motorized). We ship efficiently from major Chinese ports including Shanghai, Tianjin, Guangzhou, and Ningbo, ensuring reliable delivery to our main markets worldwide.
