As a specialized manufacturer with over a decade of experience in electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our Epoxy Resin Insulated LBS Disconnector series. Designed for reliability in medium voltage distribution systems, this product embodies our commitment to quality and safety, backed by a robust ISO9001-certified manufacturing process. Serving diverse global markets from North America to Southeast Asia, we understand the critical need for durable switching solutions that perform under demanding conditions.
Our Load Break Switch Disconnector is engineered to provide a safe, visible air gap isolation point, combining the excellent dielectric and mechanical properties of epoxy resin insulation with a robust switching mechanism. Available in 15kV, 20kV, and 36kV ratings, it offers flexibility for various network configurations. The primary value lies in its enhanced safety profile, reduced maintenance requirements, and long service life, making it a cost-effective cornerstone for modern electrical infrastructure.
Core Features and Technical Advantages:
- Superior Epoxy Resin Insulation: The switch contacts and live parts are cast in high-grade epoxy resin. This provides exceptional resistance to tracking, moisture, and environmental contaminants, ensuring stable insulation performance over decades and minimizing the risk of internal faults.
- Visible Isolation and Safe Operation: The design ensures a clear, visible break between contacts when in the "OFF" position, a crucial safety feature for maintenance personnel. The operating mechanism is interlocked to prevent accidental operation under load.
- Modular and Flexible Design: The disconnector can be supplied as a standalone unit or integrated into ring main units (RMUs) and compact substations. Options for manual or motorized operation (upon request) allow for remote control and automation integration.
- High Mechanical Endurance: Constructed with durable materials for the contacts, blades, and operating linkages, the switch is rated for frequent operation without performance degradation, suitable for applications requiring regular network reconfiguration.
- Compact Footprint: The epoxy resin insulation allows for a more compact design compared to air-insulated alternatives, saving valuable space in substations and on poles.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of epoxy resin insulation over other types?
A: Epoxy resin provides a solid, sealed insulation system that is highly resistant to environmental factors like moisture and pollution. It eliminates the risks associated with liquid or gas insulation (leaks, maintenance) and offers excellent long-term dielectric stability. -
Q: Can this disconnector be used to interrupt load current?
A: This unit is primarily designed as a disconnector to provide a visible isolation point. It can make and break negligible currents. For load-breaking or fault-making duties, it must be used in conjunction with a suitable load break switch or circuit breaker. -
Q: Is the motorized operation option available for remote control?
A: Yes, a motorized operating mechanism is available as an optional feature. This allows for integration into SCADA systems and remote operation, enhancing automation and reducing on-site personnel requirements. -
Q: What are the typical applications for this product?
A: Common applications include incoming/outgoing feeder isolation in distribution substations, section points in overhead or underground distribution lines, and as part of Ring Main Units (RMUs) for network flexibility and reliability. -
Q: How does the visible break feature work, and why is it important?
A: When the switch is open, the moving contact blade is physically separated from the fixed contact, creating a clear air gap that is visible to the operator. This is a critical safety feature to confirm the circuit is de-energized before maintenance work begins. -
Q: What is the expected service life of this disconnector?
A: With its epoxy resin insulation and robust mechanical design, the disconnector has a very long service life, often exceeding 30 years under normal operating conditions, with a mechanical endurance of over 10,000 operations. -
Q: Do you provide customization for different current ratings or special mounting requirements?
A: Yes, as a manufacturer, we offer customization. Parameters like rated current (e.g., 1250A), specific short-circuit ratings, or special mounting brackets can be discussed and developed based on your project specifications. -
Q: What certifications support the quality of this product?
A: Our manufacturing processes are certified under ISO9001 for quality management and ISO14000 for environmental management. These systems ensure consistent product quality, traceability, and adherence to international standards.
