Product Detail

Product Overview

The RLS-24B is an advanced indoor high-voltage SF6 load switch designed for 12kV/24kV power distribution systems. Utilizing SF6 gas as both an arc-extinguishing and insulation medium, it integrates three contactors (switching-on, switching-off, and grounding) in a compact, easy-to-install design. The RLS-24B and its variant, the RLS-12/24B (load switch + fuse combination), provide reliable protection and control for power supply equipment and substations, making them ideal for ring main units (RMUs), cable branch cabinets, and switching substations.

Compliant with GB3804-1990, IEC60256-1:1997, GB16926, and IEC60420, this switchgear ensures high performance in diverse electrical environments.

 

Key Features

  • SF6 Gas Technology– Superior arc-extinguishing and insulation properties

  • Compact & Lightweight– Space-saving design for easy installation

  • Triple Contactor System– Switching-on, switching-off, and grounding in one unit

  • High Adaptability– Suitable for harsh environments with minimal maintenance

  • Fuse Combination Option (RLS-12/24B)– Enhanced protection for transformers and cables

 

Product Advantages

  • Reliable Performance– SF6 ensures stable operation with minimal wear

  • Easy Operation– Simple mechanism reduces maintenance needs

  • Versatile Protection– Fuse-compatible model prevents overload damage

  • Wide Compliance– Meets GB, IEC, and international standards

  • Robust Construction– Resists humidity, altitude (up to 2500m), and mild corrosive conditions

 

Application Scenarios

  • Ring Main Units (RMUs)– Secure switching in urban power grids

  • Cable Branch Cabinets– Reliable power distribution for industrial zones

  • Switching Substations– Safe load control in medium-voltage networks

  • Transformer Protection– Fuse-integrated model prevents fault escalation

 

Environmental Specifications

  • Operating Temperature: -5°C to +40°C

  • Humidity Tolerance: Daily avg. 90% / Monthly avg. 95%

  • Max. Altitude: 2500m

Hi everyone, I’m Felix, and I’ve been working in electrical equipment fault repair for 15 years.Over these years, I’ve traveled across factories, substations, and distribution rooms all over the country, troubleshooting and repairing all kinds of electrical equipment. Dry-type transformers are among the most common devices we deal with.Today, a friend asked me:“What does it mean when the low-voltage side of a dry-type transformer has low insulation resistance?”Great

What tests are required for dry-type transformers?
1 Pre - commissioning InspectionAs a front - line tester, before formally commissioning a dry - type transformer, I need to carry out a comprehensive and systematic inspection. First, I conduct a visual inspection of the transformer body and its accessories, carefully checking for mechanical damage or deformation. Then, I check whether the leads of the high - and low - voltage windings are firmly connected and whether the bolt tightening torque meets the standard requirements (usually 40 - 60N&m

What aspects need attention during the installation of dry-type transformers?
1 Pre - installation PreparationAs a front - line installer, I know very well that the preparation work before installing a dry - type transformer must be thorough. First, I will carefully review the design drawings and technical documents, and check one by one the technical parameters such as the model specification, rated capacity, and voltage level of the transformer to ensure they are in full compliance with the design requirements. Then, I will conduct an unpacking inspection of the transfo

What are the causes of dry-type transformers burning out during operation?
1 Fault PhenomenonI am engaged in front - line fault maintenance work, and recently encountered problems with dry - type transformers. Dry - type transformers have a simple structure, are convenient for transportation, and easy for maintenance. They are widely used in power distribution places with relatively high environmental protection requirements. Because of their good fire - resistance, they can be installed in load - center areas to reduce voltage loss and power loss.The property manageme
