Prefabricated Electrical Substation Box 4000A Rated Current For Power Distribution
Box-type substation, also known as pre-installed substation. It is a combination of high-voltage switch gear, distribution transformer and low-voltage power distribution device.
It is an indoor and outdoor compact power distribution equipment prefabricated in the factory,which is integrated according to a certain wiring scheme. It combines the functions of transformer step-down and low-voltage power distribution organically.
This power substation package is installed in a steel structure box that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable.It is especially suitable for urban network construction and renovation.
It is a new type substation to replace the civil construction substation. The box-type substation is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil power distribution room and substation and becomes a new type of transformer distribution equipment.
Box-type substation is also suitable for residential quarters, urban public, bustling downtown, construction power supply, etc.Users can choose box-type substation according to different usage conditions and load levels.
Below are the tests conducted by Varelen before delivery. Other tests required by clients can also be done accordingly.
Resistance of all windings
Check voltage ratio and vector group
No-load test at rated frequency and rated voltage
Withstand voltage test
Induced over-voltage withstand test
Partial discharge measurement
1. Intelligient control, integrated with enclosure, compact structure and high environmental adaptability for outdoor applications.
2. The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel laminations insulated on both sides, guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with a flash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise.
3. Clamping frame: it is processed by CNC cutting, bending and then one-time punch forming, the hole’s size is accurate and the appearance looks delicate.
4. The winding coil is made of oxygen-free copper, class H for main insulation materials and coil is insulated by NOMEX paper of DUPONT brand, LV winding is isolated by copper foils. All these make the heat-resistant is up to 220℃, with excellent overload capacity and low loss, but high efficiency.
5. Varelen practices strictly exclusive casting system of F(155℃) or H(180℃), and the epoxy resin is injected and casted in the vacuum machine, so it’s highly insulated, dust-proof and moisture-proof, which ensures stable and reliable performance.
The shell of the box is made of aluminum-coated zinc steel plate and container manufacturing technology, and the design is beautiful. On the premise of ensuring the reliability of power supply, the shell color of the box-type substation is selected, so that it is easy to be in harmony with the surrounding environment Especially suitable for urban construction.
Such as: Urban residential areas, stations, ports, airports, parks, green belt and other densely populated areas, it can be used as a fixed substation, can also be used as a mobile substation, with decorative and beautifying the environment.
