Introduction
SF6 high-voltage load switch: SF6 gas is used to extinguish the arc, which has large interrupting current and good interrupting capacitance current performance, but its structure is complicated, and it is suitable for products of 35 kV and above.
Robust Construction and Design
The FLN36 – 12D/T load – break switch features a robust construction. The outer casing is made of high – quality insulating materials that provide excellent electrical insulation and mechanical protection. The internal components are carefully selected and assembled to ensure reliable operation over a long service life. The design of the switch also takes into account ease of installation and maintenance, with accessible connection points and a simple structure that allows for quick inspection and troubleshooting.
Technical Specifications
- Model: FLN36 – 12D/T
- Rated Frequency: 50HZ. This frequency is widely used in power grids around the world, ensuring compatibility with most electrical systems operating in the same frequency range. It allows for stable and efficient power transfer and distribution within the electrical network.
- Rated Dynamic Stable Current (2s): 50kA. The switch is capable of withstanding a high – intensity dynamic current for a short period of 2 seconds. This high – current – handling ability is crucial in electrical systems where sudden current surges may occur, such as during short – circuit events or when large electrical equipment is started up. It ensures the safety and integrity of the switch and the overall electrical system.
- Rated Voltage: 12KV. With a rated voltage of 12KV, the FLN36 – 12D/T load – break switch is suitable for medium – voltage electrical applications. It can effectively control and isolate the power supply in indoor power distribution systems operating at this voltage level.
- Arc – extinguishing Feature: Without arc – extinguishing function. Although it does not have an in – built arc – extinguishing mechanism, it is designed to operate safely within its rated parameters. In applications where arc – extinguishing is not a primary requirement or where additional arc – suppressing measures are in place, this switch can provide reliable power control.
- Application Environment: Indoor. Specifically designed for indoor use, the switch is protected against environmental factors such as dust, moisture, and direct sunlight. Its housing and internal components are engineered to perform optimally in controlled indoor environments, making it a suitable choice for various indoor electrical installations like industrial control rooms, commercial buildings’ electrical substations, etc.
- 3C Rated Voltage Range: AC above 1000v. This indicates that the switch meets the 3C certification requirements for voltage levels above 1000 volts in alternating – current systems. The 3C certification ensures the safety, reliability, and quality of the product in the Chinese market.
- Dynamic Contact Structure: None. The switch’s design is optimized for its intended functionality without a specific dynamic contact structure, which simplifies its operation and maintenance while still maintaining reliable performance.
- Mode of Operation: Manual. The manual operation mode provides a straightforward and reliable way to control the switch. Operators can directly and precisely open or close the switch as needed, which is especially useful in applications where quick and simple control is required or in situations where automation is not necessary or practical.
- Number of Poles: 3. With three poles, the switch is suitable for three – phase electrical systems, which are commonly used in industrial and commercial power distribution. It can simultaneously control and isolate the three – phase power supply, ensuring balanced and stable power distribution.
- Customs Code: 85372090. This customs code is used for international trade and identification of the product, facilitating smooth import and export procedures.
Applications
- Industrial Settings: In industrial plants, the FLN36 – 12D/T load – break switch can be used to control the power supply to various production lines, motors, and other electrical equipment. It can isolate specific sections of the electrical system for maintenance or fault – finding purposes, ensuring the safety of maintenance personnel and minimizing production downtime.
- Commercial Buildings: In commercial buildings such as office complexes, shopping malls, and hotels, this switch can be installed in electrical substations or distribution panels. It helps manage the power distribution to different areas of the building, ensuring a stable and reliable power supply for lighting, HVAC systems, and other electrical loads.
In conclusion, the FLN36 – 12D/T load – break switch is a reliable and practical solution for indoor medium – voltage electrical applications. Its well – defined technical specifications, robust construction, and user – friendly operation make it an ideal choice for a wide range of electrical control and isolation needs in indoor environments.
