Product Overview

The 252 kV GIS used 50Hz 220kV three phases current of power system. Live conductors of this product are contained in a sealed metal container and filled with SF6 gas as insulating and interrupting medium. Modular design according to main connection requirements of substation can assemble different kinds of structures. This equipment includes circuit breaker, disconnector, maintenance or fault earthing switch, current transformer, voltage transformer, lighting arrester, busbar and inlet/outlet BSG or cable end box, bellows, local control panel etc., components. This product can be applied to power system, power generation, rail transportation, petrochemical, metallurgy, mining, building materials and other large industrial consumer.

Features and advantages of the product

1. Extremely small volume very light weight

Small type GIS compared with other domestic conventional GIS, has extremely small volume. The enclosure and conductor are equipped with composite aluminum, corrosion-proof, very light weight. Sharply decreased the space needed and earth load capacity of substation and meet small substation requirements.

2. Superior interrupting capability

Circuit breaker is characterized by air compressed arc-extinguishing principle, has superior interrupting capability and making capability, electric endurance is 20 times. Disconnector can switch busbar transfer current and busbar charge current. Fast earthing switch can make short circuit current and can switch induced current.

3. High insulation level

Insulation construction is characterized by good design. All insulation parts have passed advanced inspection methods and extreme test for quality. Insulation is of stability and reliability. Level of withstand voltage for GIS surpass DL and GB standard.

4. High safety Performance

Live conductors are contained in sealed container, no electric shock danger. Filled with inert gas SF6 as insulating medium, and no fire danger.

5. Easy maintenance and long inspection cycle

Circuit breaker used hydraulic spring operating mechanism without leakage, stable and reliable breaking capability; enclosure is of superior sealing construction, so inspection cycle is long. Small sized design and low whole height, so maintenance work is convenient.

6. Short period of site installation

By fully use of whole bay assembling and deliver to the site with unit or whole bay form after qualified test, thereby period of site in stallation is short.

Quality Assurance Period (QAP) Explanation

1.    The Quality Assurance Period (QAP) is an important aspect of our commitment to ensuring the quality and reliability of our products. We understand that customers rely on our goods to function properly and meet their expectations. To demonstrate our confidence in our offerings, we provide a warranty period during which we take responsibility for any quality issues that may arise.
2.    The length of the warranty period varies depending on the type of product. Generally, for consumable components subject to wear and tear, such as abrasion parts, the warranty period is three months. For smaller components, the warranty period is typically extended to six months. As for major equipment and machinery, we offer a one-year warranty period.
3.    We also recognize that each customer's requirements may differ, and we are open to negotiation regarding the warranty period. If the buyer requests a specific warranty duration that differs from our standard policy, we are willing to discuss and accommodate their needs accordingly.
4.    During the warranty period, we take full responsibility for any quality-related issues that arise. If a product is found to be defective or malfunctions due to manufacturing or material faults, we are committed to providing a resolution. This includes either replacing the faulty component or conducting necessary repairs to restore the product to its intended functionality. Our aim is to minimize any inconvenience caused to our customers and ensure their satisfaction.
5.    It is important to note that the warranty does not cover damages resulting from improper use, mishandling, or normal wear and tear. Additionally, if any modifications or repairs are carried out by unauthorized personnel during the warranty period, the warranty may become void.
6.    At our company, customer satisfaction is our top priority. We strive to provide high-quality products that meet and exceed expectations. The Quality Assurance Period serves as a testament to our commitment to delivering reliable solutions and ensuring that our customers have peace of mind when choosing our products.
