Product Detail

Description:

UniGear 500R is very space efficient solution, designed to reduce the width of the medium-voltage airinsulated switchgear. Panel design is only 500 mm wide for feeder current up to 2000 A.Its compact design makes UniGear 500R ideal for container installation for primary distribution.  

One of the main characteristics of the UniGear 500R switchgear is the isolation of the circuit-breaker from the main busbars by means of the three position disconnector.

FAQ
Q: What’s the difference in the circuit breaker for air-insulated vs gas-insulated?
A:
Air-insulated switchgear circuit breaker is typically removable or withdrawable. The circuit breaker is based on vacuum circuit technology. In the gas-insulated, it is fixed mounted. The function of withdraw is provided by a separate disconnecting switch. Typically, a three-position switch with connected, disconnected, and ready-to-earth position.
Q: What are the key features of ABB’s medium voltage switchgear products?
A:
ABB‘s primary medium voltage switchgear products are designed to connect and protect the evolving grid. They feature robust construction, advanced safety mechanisms, high reliability, and ease of maintenance. They are designed to handle high electrical loads and provide efficient power distribution with minimal losses.

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?
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
