Product Detail

Overview

Small in Size To compare with AIS Substation, it can save 60 - 70% of the floor area, best way for saving current increasingly tense land resources;

Fast Way To transport the Combined bay. All HGIS components have been debugged and tested in the Factory. Only a few line connections and routine tests are required on - site, therefore, the on - site installation time of single bay can be ≤ 10h; 

Stability in Performance The Circuit Breaker is the HGIS core component, which is horizontally arranged, with low center of gravity, better stability and better seismic performance. It is especially suitable for earthquake - prone areas (Have accepted and passed the ACS test). The Circuit Breaker can be used in extremely harsh environments (Sandstorm, heavy pollution, etc.), thanks for its fully enclosed transmission way.

Convenience in Replacement It is designed solely with anchor bolt fixing and overhead incoming and outgoing lines, with independent bays, therefore, the replacement of single bay can be completed within 4h. Also not be troubled as GIS Substation, which can be troubled by the long power outage time caused by GIS Substation failure, the transformation and expansion of the Substation is relatively simple and convenient, especially suitable for the AIS Substation. It only needs simple civil foundation work with small investment, so it's worth it;

Reliable in Quality The HGIS is specialized designed is relative perfectly, with SF6 gas insulation for its excellent insulation and breaking performance.

Lower Life - cycle Costs Refer to GIS and AIS, the HGIS has the multi features, such as minimum maintenance workload, minimum construction difficulty, shortest construction time, minimum overhaul difficulty, lower equipment cost, lower operation cost and shorter construction period for reconstruction and expansion.

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
