Application
Load-break disconnector switches are specifically designed for low-load breaking in overhead medium voltage (MV) electrical lines. Featuring an integrated air-break technology system and a series-mounted isolating switch, these devices ensure visible opening and enhanced operational safety. The ISAR-S (IACM) switches are particularly suited for overhead distribution networks up to 36 kV, where a high level of insulation is paramount.
Usual Service Conditions
• Ambient temperature range: -25°C to +40°C
• Altitude: Up to 1000 meters above sea level
• Wind speed: Up to 35 m/s
• Pollution level: Moderate to heavy
• Seismic activity: Compliant with zone 4 requirements
Advantages
• Maintenance-Free: No routine maintenance required, reducing operational costs.
• Easy Installation: Simplified pole top mounting for quick and efficient setup.
• Enhanced Safety: Line works can be carried out in safe conditions due to the visible opening and high insulation level.
• Manual Control Mechanism: Equipped with a rod assembly and a padlockable lever for secure operation.
• Whip Breaking System: Effective in managing dynamic forces during operation.
• Tumbler Spring System: The control mechanisms are fitted with a tumbler spring system that directly operates the mobile shaft, ensuring consistent operating speed regardless of the operator.
• Versatile Pole Height Compatibility: Suitable for poles ranging from 11 to 14 meters in height.
• Durable Insulators: Synthetic insulators with a central part made of epoxy resin and flexible skirts in over-molded silicone offer significant creepage distance and robust protection against vandalism.
Additional Features
• No maintenance required.
• Easy pole top mounting.
• Line works can be carried in safe conditions thanks to the visible opening and high level of insulation.
• A manual control mechanism is available with a rod assembly and padlockable lever.
• Whip breaking system.
• The ISAR-S switch control mechanisms are equipped with a tumbler spring system which directly operates the mobile shaft. The operating speed is not dependent on the operator.
• Height of the pole from 11 to 14 m.
• Synthetic Insulators designed with a central part in epoxy resin. The flexible skirts in over-molded silicone provide an important creepage distance and good protection against vandalism.
This revised product description now includes detailed information on usual service conditions and advantages, providing a more comprehensive overview for potential users.
Insulation Performance
The ISAR-S switches and similar load-break disconnector switches are characterized by their excellent insulation performance, which includes the following features:
High Insulation Level: These switches are specifically designed for overhead distribution networks requiring high insulation levels, capable of withstanding voltages up to 36kV.
Synthetic Insulator Design: The switches incorporate synthetic insulators with a central part made of epoxy resin, a material known for its superior insulation properties.
Silicone Over-molded Skirts: The flexible skirts of the insulators are over-molded with silicone, providing an important creepage distance and offering good protection against electrical shocks and vandalism.
Visible Disconnection: The device features a visible break, ensuring that the circuit is clearly and visibly open during operation, which enhances operational safety.
Maintenance-Free: Thanks to their optimized design, these switches require no regular maintenance under normal service conditions, reflecting the stability and durability of their insulation materials.
Adaptability to Various Environmental Conditions: While specific environmental adaptability is not detailed in the provided information, these switches are generally designed to operate effectively under a range of common environmental conditions, including certain temperature ranges, altitudes, and pollution levels.
Overall, the ISAR-S switches and similar load-break disconnector switches offer outstanding insulation performance, making them suitable for power systems that demand high insulation levels and safe operation. For more specific insulation performance data, such as insulation resistance values and withstand voltage levels, it is advisable to refer to the manufacturer's technical manual or conduct further inquiries.
