As a leading manufacturer in the electrical equipment industry, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents the FLN36-12/24 Indoor Load Break Switch, engineered for reliable and safe operation in medium-voltage distribution networks. With over a decade of expertise and a commitment to stringent quality control under internationally recognized management systems, we deliver robust solutions tailored for utilities and industrial facilities. Our FLN36 series is designed to meet the demanding requirements of modern 11kV and 33kV AC networks, offering superior performance, ease of maintenance, and enhanced safety for operators and equipment alike.
The FLN36-12/24 Load Break Switch is a cornerstone for secure power distribution. Its core value lies in providing a visible isolation point and reliable load-breaking capability, which are critical for network segmentation, maintenance safety, and operational flexibility. Key features and benefits include:
- Robust Construction & SF6 Insulation: The switch utilizes a sealed, maintenance-free SF6 gas chamber for both insulation and arc extinction. This design ensures consistent dielectric strength, excellent arc-quenching performance, and reliable operation in various environmental conditions, significantly reducing the risk of internal faults.
- High Safety & Visible Isolation: The three-position switch (ON, OFF, EARTH) provides clear visual indication of the contact position. The integrated earthing switch allows for safe grounding of the isolated circuit, a vital safety feature for maintenance personnel, complying with the highest safety protocols.
- Long Mechanical & Electrical Life: Engineered for durability, the switch boasts a mechanical life exceeding 10,000 operations. The contacts are made of special alloys resistant to welding and erosion, ensuring a long electrical service life even under frequent switching cycles.
- Compact Indoor Design: Specifically designed for indoor substations, compact switchgear rooms, or industrial plant installations. Its space-saving footprint allows for efficient panel integration and easier retrofitting into existing infrastructure.
- Flexible Integration & Control: The switch can be equipped with manual, motor-operated, or remote-controlled spring-charged mechanisms. It is readily integrable with protection relays and SCADA systems for automated distribution network management.

Frequently Asked Questions (FAQ)
-
Q: What is the primary application of the FLN36-12/24 Load Break Switch?
A: It is primarily used in indoor substations and industrial plants for sectioning, connecting, and disconnecting live parts in 11kV and 33kV AC distribution networks. It provides a visible break for isolation and safe maintenance. -
Q: Can this switch interrupt fault currents?
A: No, a load break switch is designed to make and break normal load currents and transformer magnetizing currents. It is not intended to interrupt short-circuit fault currents. For fault protection, it must be used in series with a suitable circuit breaker or fuse. -
Q: Is the SF6 gas sealed for life, and is maintenance required?
A: Yes, the switch features a sealed, maintenance-free SF6 gas chamber. It is designed for a long service life without the need for gas refilling under normal operating conditions. -
Q: What are the available control options for the operating mechanism?
A: The switch is typically supplied with a manual spring-operated mechanism. Options for motor-operated mechanisms for remote control are available upon request to facilitate automation. -
Q: What standards does this product comply with?
A: The FLN36-12/24 is designed and tested in accordance with international IEC standards, specifically IEC 62271-1 (common specifications) and IEC 62271-102 for alternating current disconnectors and earthing switches. -
Q: Can it be integrated into existing switchgear panels?
A: Yes, its compact and fixed-type design allows for relatively straightforward integration into both new and existing metal-clad or metal-enclosed switchgear panels. Detailed installation drawings and dimensions can be provided. -
Q: What is the typical delivery time for an order?
A: Delivery time depends on the order quantity and specific configuration. Standard models typically have a shorter lead time. We strive to provide accurate timelines upon receipt of your inquiry. -
Q: Do you provide technical support and documentation?
A: Absolutely. We provide comprehensive product manuals, technical data sheets, and certificates of compliance. Our engineering team is available to offer support for installation, operation, and integration queries.
