5 ASN3 & ASN2 Product Design Designed with Detachable Apparatus, Safety Shutter, Epoxy-Insulated Busbars, Robust and Boltless Frame, Efficient Ventilation System, Safer Pressure Relief Ducts, and Reliable Interlocks. Customized Parts are by Designated Suppliers. Detachable Apparatus The low voltage control compartment is made up of detachable parts. Assemble the parts together before connecting the wires. Then you install the compartment into the switchgear, making it neat, tidy, and convenient for the service technician to perform maintenance work. Since all parts position are fixed, assembly is straightforward and thus more efficient. Safety is assured with all wirings arranged in metal covered wiring slots preventing bare wires from being exposed to service technicians. Detachable Instrument Compartment Safety Shutter The circuit breaker rails and metallic shutter in front of the stationary contacts have been designed to isolate the breaker compartment from the busbar compartment to increase service technicians safety during maintenance work. Whenever the circuit breaker is withdrawn from its service position, the shutter will close automatically, enclosing the static contact box, thus meeting the safety requirements of IP2X. This prevents accidental contacts with the switchgear energized stationary contacts. Pad lock can be installed at the shutter to prevent unauthorized personnel from accessing the switchgear, hence preventing accidents. Circuit Breaker Safety Shutter Page 5

ASN Series - The Next-Generation MV Switchgears Epoxy-Insulated Busbars The busbars are epoxy-insulated. This insulation has a higher density, adhesion, high heat resistance, and is durable.

and nuts design that cause gaps to be present between switchgear panels when joined together.

The boltless frame design enables the switchgear panel to be removed and replaced by the service technician with ease.

6 ASN Series - The Next-Generation MV Switchgears Epoxy-Insulated Busbars The busbars are epoxy-insulated. This insulation has a higher density, adhesion, high heat resistance, and is durable. Epoxy-Insulated Busbars Robust and Boltless Frame Boltless Switchgear Frame The frame has been constructed with aluminum coated zinc plates joined by steel rivets which eliminate the protruding bolts and nuts design that cause gaps to be present between switchgear panels when joined together. Steel riveting has the advantage of distributing the stress evenly to all parts, thus increasing the frame s robustness. The boltless frame design enables the switchgear panel to be removed and replaced by the service technician with ease. Even if the switchgear panel is between other switchgear panels inside the medium voltage substation, the complete switchgear panel can be drawn out and replaced easily as required. The front and rear doors have been strengthened with special techniques to improve their mechanical strength to satisfy the Internal Arc Test. Safe Pressure Relief Ducts Pressure relief ducts have been set up above the circuit breaker, busbars, and cable compartments. In the event when an electric arc occurs, the pressure within the switchgear will increase, causing the door sealing mechanism (installed at the front door) to be activated, sealing the switchgear doors. The pressure relief ducts at the top of the frame will automatically be opened, relieving both pressure and heat. This prevents injury to the operator(s) and reduces the dangers to the switchgear. Safe Pressure Relief Ducts Page 6

This process dissipates heat from the system enabling the switchgear to function as designed.

7 Efficient Ventilation System The base of the circuit breaker compartment has been designed with air passages. When the temperature rises during operation, the hot air rises while cold air enters from the base into the compartment. This process dissipates heat from the system enabling the switchgear to function as designed. Efficient Ventilation System Customized Parts by Designated Supplier By designating supplier for current transformer (CT), CT dimension is defined for all current rating. Product quality is assured by unifying the measurement/dimension of the CT busbar. Installation is easier, resulting in shorter product delivery time. The new earthing switch consists of a high fault making switch with a fast closing mechanism and a compact structure that is easy to operate. In addition, an exquisite appearance. Customized Earthing Switch To raise the overall switchgear quality, the switchgear is installed with well-known brand secondary parts to assure the reliable operation of its secondary circuit.

8 ASN Series - The Next-Generation MV Switchgears Safe and Reliable Interlock The switchgear is installed with mechanical and electric interlocks to prevent mis-operations. This satisfies the requirements of Five Preventions : (1) prevent mis-operation of the circuit breaker; (2) prevent mishandling when loading or unloading the circuit breaker truck; (3) prevent closing of earth switch when under voltage; (4) prevent power from being supplied when earth switch is at earth position; and (5) prevent physical access to the live compartment. These measures will further protect the safety of the operators and the switchgear. There are clear positions marked for service and test functions on the circuit breaker. The built-in mechanical lock will ensure that closing operations can only be carried out when the circuit breaker is in service / test mode. Above all, the circuit breaker can only unload when it is in the open mode. Reliable Interlocks A mechanical lock has been installed between the circuit breaker truck and the secondary controlling plug to prevent the plug from being unplugged when the circuit breaker is in operation. This ensures safety measures are in operation whenever the switchgear is in operation mode. Page 8
