The appearance of three types of switchgear equipment: 40.5kV SF6 Gas Insulated Metal-clad switchgear and KYN61 Air Insulated Switchgear Structure Introduction

1. 40.5KV 1250A-4000A Cabinet-type SF6 Gas Insulated Metal Enclosed Switchgear (referred to as C-GIS)

2. 40.5KV 630A SF6 Gas Insulated Ring Main Unit

3. KYN61 -40.5 Armored Withdrawable Metal Enclosed Switchgear

4. Comparison of overall dimensions between 40.5kV Sf6 Gas Insulated Metal-clad switchgear and KYN61 Air Insulated Switchgear

5. Comparison of application sites between 40.5kV SF6 Gas Insulated Metal-clad switchgear and KYN61 air cabinets

a. 40.5KV SF6 Gas Insulated Metal Enclosed Switchgear is a high-tech complete power distribution device that has newly developed internationally in the 1990s. It is characterized by modularity, multifunctional combination, high reliability, and compact structure, representing the development direction and world advanced level of the new generation of medium voltage switchgear, and has become an important branch of medium voltage metal enclosed switchgear.

b. The high-voltage live parts of 40.5kV SF6 Gas Insulated Switchgear are completely sealed in a sealed gas tank filled with low-pressure SF6, making it particularly suitable for environments such as underground, plateau, permafrost, coastal, and humid areas, as well as densely populated areas and places with expensive building space.

c. In recent years, many large and medium-sized cities in China have newly opened urban rail transit, with the

operating mileage of urban rail transit exceeding 4500 kilometers. Due to the dense urban population and small

usable area, 40.5kV Gas Insulated Switchgear has been widely used because of its small size.

d. Over the past decade, the installed capacity of wind power and solar energy in China has been increasing year by year. Since wind and photovoltaic equipment are generally installed in harsh environments such as high mountains and seas, 40.5kV SF6 Gas Insulated Ring Main Units have been widely used.

e. KYN61-40.5 is only suitable for altitudes ≤1000m, and is not suitable for places with high humidity, corrosion,

severe pollution, flammable gases, and severe vibration.

II. Structural Features of Our Company's 40.5kV C-GIS

1. Low-pressure SF6 gas insulation;

2. Modular design;

3. Stainless steel welded gas chamber structure, with double and triple gas chamber structures where the circuit breaker and three-position switch are installed in their respective independent gas chambers, and the gas chambers are connected using patented technology;

4. The cabinets are connected using plug-in solid insulated busbar connectors, and the switchgear assembly does not involve SF6 gas filling;

5. Each assembled cabinet can be individually disassembled without moving adjacent switchgear;

6. Special internal cone type (40.5kV) cable connectors, reliable connection;

7. Maximum safety and reliability: independent functional units, high-voltage primary components unaffected by environmental conditions, etc.;

8. Minimum installation space: using SF6 gas as the insulating medium, the cabinet size is smaller, the cabinets are connected using plug-in busbar connectors, the layout is more compact, practical cables are used for external primary connections, installation is more convenient, and compared with traditional switchgear, the floor area is reduced by 30-70%;

9. Better economy: minimal operation and maintenance costs, maintenance-free, long service life, small footprint, and low construction cost
