Applications: Power stations generate electrical power, with voltages up to 500,000V, which is transmitted to transformer stations and dispersion stations. These substations distribute medium voltage above 1kV to 36kV and it is here that a number of INESING Medium Voltage Switchgear cubicles can be used. A medium-voltage grid starts from every substation and supplies a large area with medium-voltage. Wherever medium-voltage enters residential areas, industrial production companies, mining sites, data centres, rail, hospitals and more, there is a medium voltage cubicle fulfilling four essential functions. 1.POWER SUPPLY: the network distributor s grid is branched off to allow switching. 2.SECURITY: the installation is secured with a load break switch with HRC fuses, or by a load break switch with a safety relay. 3.MEASUREMENT: the energy consumption is measured on the high-voltage, or low-voltage side. 4.TRANSFORMATION: medium-voltage is transformed into low-voltage (1,000V-400V-230V).

INESING MEDIUM VOLTAGE SWITCHGEAR OVERVIEW DESIGN PHILOSOPHY AND APPLICATIONS User-friendliness, safety and care far the environment were the main mativators in the selection of INESING Medium Voltage Switchgear. INESING can provide made-tomeasure solutians far oll your medium-voltage needs. INESING Medium Voltage Switchgear offers a wide range of applications that can be used worldwide in many industries. Cubicles can be used with distribution and dispersion switchgear, electrical sub-stations and medium-voltage engines, wind generators, cogeneration, and much more. The INESING Medium Voltage Switchgear range provides a solution for oll your needs and demands as it can replace obsolete installations, extend existing installations, and it is also perfectly suited for brand new installations. The INESING Medium Voltage Switchgear cubicles are a madular concept based on the building blocks principle, which means that cubicles are produced in series. As a result these products meet the highest technical standards in a rational and economically sound way. The combinatian of cubicles is unlimited. Very camplex diagrams of distribution and transformer switchgear can be campiled through this extensive spectrum of possibilities. Cubicles contain standard functional interlocks which allows for effortless application and installation in most consumer work spaces. As a result, capacity loss will be minimal. Additionally, the cubicles have been fitted with a system for pressure release which shields the user from the consequences of an internal arc. w w w. i n e s i n g. 7 c o m
INTERNAL ARC MITIGATION OPTION WITH BUILT-IN ARC-KILLER A short-circuit or another malfunction can create an internal arc. An internal arc in a Medium Voltage cubicle could severely damage the installation and possibly injure the operator. INESING Medium Voltage Switchgear cubicles are designed to mitigate the creation of internal arcs and therefore protect both the operator and the installation. Through a strategic pressure release system, the internal arc is restricted to the compartment where it originated and it does not spread towards the operator or to other compartments. The cubicles are specifically designed to minimize the consequences of an internal arc. All provided cubicles are fitted on the rear side with overpressure valves pointing downward as a standard. INESING Medium Voltage Switchgear cubicles have been tested with these specifications at independent, and accredited testing solutions (for examplecesi - KEMA). The load break switches have been tested according to IEC standards and consequently, all INESING Medium Voltage cubicles are internal arc resistant. Protect your cubicles, infrastructure and your staff against the consequences of an internal arc. The built-in Arc-Killer extinguishes an arc in less than 50ms. The INESING Medium Voltage Switchgear range includes the Arc-Killer SV-25 and SV-53, a system for detecting and extinguishing an internal arc. The Arc-Killer extinguishes the arc by directing it to a metal earthed short circuit. The arc is extinguished in less than 50ms. Our modules are metal enclosed cubicles combined with a shaft at the rear end. The shaft absorbs any gasses (in case of an internal arc) that escape through the overpressure valves. As a result, the expansion of hot gasses in a room can be reduced to an absolute minimum. INESING Medium Voltage Switchgear cubicles offer protection against an internal arc classification IAC category B, FLR 25 ka 1 s. (F=frontal, L=lateral, R=rear). As a result, the operator is protected against the consequences of an arc whether they stand in front of the switchboard, next to it or behind it. Without Arc-Killer With Arc-Killer The patented SV-25 and SV-53 Arc-Killer takes safety to a new level. Not just the operator and the environment are shielded from harm, but the super-swift arc extinguishing system allows cubicles to be back in operation very quickly in case of an internal fault. What s more, the Arc-Killer s improved security features place less strict demands on the installation room. As such, the Arc-Killer couples security and operational safety with flexible room demands.

COMPARTMENTS SWITCHGEAR COMPARTMENT In this compartment, the gas filled load break switch is double sealed, which acts as the physical separation between the busbar set and the cable compartment. The switch has two functions: it connects or interrupts the electrical current between the high voltage cables and the busbar. BUSBAR COMPARTMENT The busbar compartment is located in the upper part of the cubicle and behind the low-voltage compartment. The modular busbar set is manufactured from specially provided electrolyte F25 copper of 60 x 10mm with n = 5mm (800A). Standard as well as 1250A option is available. Several cubicles are connected through the bar set compartments. Hexagonal bolts connect the busbars to the upper contact surfaces of the load break switch. CABLE COMPARTMENT The cable compartment is located behind the interlocked, removable door of the cubicle. This part of the field receives the cable(s) and contains the necessary equipment to connect the cable(s). The earthing switch is installed below the load break switch on the right side, ensuring a visible earthing when the earthing switch is closed. In a cubicle, the cables are connected to the contact points below the load break switch. The cables of the cubicles are connected to the lower fuse base side. This type of cubicle also has an additional auxiliary earthing switch to divert any residual current. This type cubicle have the earthing switches located in the cable compartment below. The removable door, the sectional floor panels which house the necessary conductive rubber for the cables, and the cable supports all simplify the cable connection. LOW-VOLTAGE COMPARTMENT The drive mechanism that controls the load break switch and the earthing switch is fitted with the synoptic diagram and is located behind the front panel. Several accessories, such as the auxiliary contacts, switch-on or switch-off coils, and minimum voltage relays are also located in this compartment. Any control with the necessary electrical switchgear, a control and clamp strip are also installed in this compartment. The compartment is easily accessible by removing the front panel.
