Product Detail

Product Overview：

The Rockwill RLS-12/17.5 is a compact, SF6 gas-insulated load break switch designed for indoor medium-voltage applications at 12kV and 17.5kV ratings. This high-performance switchgear utilizes SF6 gas for effective arc quenching and insulation, featuring a three-position switching mechanism (make-break-ground) in a space-saving design that ensures easy installation and reliable operation in various environments. The standard RLS-12/17.5 model and its fused combination variant (RLS-12/17.5D) provide comprehensive protection and control for power distribution networks, particularly suitable for ring main units, cable branch cabinets, and distribution substations.

Key Features:

  • Three-position switching mechanism (ON-OFF-GROUND)

  • SF6 gas insulation for superior arc extinction

  • Compact and lightweight design

  • Optional fused combination (RLS-12/17.5D)

  • Compliant with GB3804, IEC60256-1, GB16926, IEC60420 standards

Product Advantages:

  1. Enhanced electrical safety with SF6 gas insulation

  2. Reduced maintenance requirements

  3. Space-efficient design for compact installations

  4. Reliable operation in demanding conditions

  5. Flexible configuration options (with or without fuse)

Application Scenarios:

  • Ring main unit (RMU) applications

  • Cable distribution networks

  • Compact substation installations

  • Industrial power distribution systems

  • Building power supply systems

Environmental Specifications:

  • Operating temperature range: -5°C to +40°C

  • Humidity tolerance: 90% daily average, 95% monthly average

  • Maximum installation altitude: 2500m above sea level

  • Suitable for non-corrosive environments

  • Vibration-resistant construction

What is the difference between a dielectric and an insulator?
What is the difference between a dielectric and an insulator?
Dielectrics and insulators are distinguished primarily by their applications. One of the main differences is that a dielectric can store electrical energy by becoming polarized in an electric field, whereas an insulator resists the flow of electrons to prevent current conduction. Other key differences between them are outlined in the comparison chart below.Definition of DielectricA dielectric material is a type of insulator that contains few or no free electrons. When subjected to an electric fi

Fault Analysis and Treatment of Oil-Immersed Transformers
Fault Analysis and Treatment of Oil-Immersed Transformers
Oil Leakage at Welded JointsOil leakage at welded joints primarily stems from poor welding quality, such as incomplete or detached welds, and defects like pinholes and gas pores. Although oil-immersed transformers are initially coated with solder and paint during manufacturing, potentially masking these issues temporarily, the defects tend to surface during operation. Additionally, electromagnetic vibration can cause weld cracks, leading to oil leakage.To resolve such leaks, the first critical s

What losses occur during operation of the transformer? How to reduce losses?
What losses occur during operation of the transformer? How to reduce losses?
Transformers experience various types of losses during operation, primarily categorized into two main types: copper losses and iron losses.Copper LossesCopper losses, also known as I²R losses, are caused by the electrical resistance of the transformer windings—typically made of copper. As current flows through the windings, energy is dissipated in the form of heat. These losses are proportional to the square of the load current (I²R), meaning they increase significantly with high

Cable Fault Detection, Testing, Location and Repair
I. Methods for Cable Testing and Inspection:Insulation Resistance Test: Use an insulation resistance tester to measure the insulation resistance value of the cable. A high insulation resistance value indicates good insulation, while a low value may suggest insulation problems requiring further investigation.Voltage Withstand Test: Apply a high-voltage test using a high-voltage tester to verify whether the cable can withstand high voltage under its rated operating conditions. Under normal circums
