oil immersed transformer

S11-M

oil immersed transformer

Oil-immersed power transformers utilize insulating oil as a cooling and insulating medium. They are widely used in power systems, industries, and new energy sectors, featuring excellent heat dissipation, large capacity, reliable insulation, and stable operation.

CT power supply

CT power supply

This voltage sensor is suitable for the isolated and precise measurement of AC, DC, and pulsating voltages, with complete insulation between the primary and secondary sides during measurement. Main applications include: variable frequency speed control devices, inverters, UPS uninterruptible power supplies, SMPS switching power supplies, electric locomotives, power grid monitoring, etc.

Pole type combination sensor

FHEPJL12-630-25

Pole type combination sensor

The FHEPJL12-630-25 Extreme Gui-style combination sensor (deep fusion type) conforms to the technical specifications of the State Grid's primary and secondary fusion equipment and is designed and manufactured according to the T/CES018-2019 standard. It integrates circuit breakers, power supply, current, and voltage, and is suitable for 10kV power systems.

high and low voltage series reactor

CKSC

high and low voltage series reactor

Series reactors are mainly used in 0.4～35kV power systems and are connected in series with high-voltage capacitor banks. They can effectively suppress and absorb high-order harmonics, limit inrush current and switching surges, protect capacitors, improve power quality, and ensure the safe operation of the power grid.

indoor single-phase current transformer

LDZC□-10

indoor single-phase current transformer

The LDZC series indoor current transformers are suitable for current measurement, energy metering, signal sampling, and microcomputer protection of 0.66-10kV power supply and distribution equipment in AC power systems. They feature small size, light weight, and easy installation, making them widely applicable in various types of ring network cabinets, switchgear, combined substations, and cable branch boxes. They are also ideal for providing accurate data measurement to the entire system via sampling units composed of remote terminal units (RTUs) and field terminal units (FTUs). Multiple installation methods and dimensions are available, along with customized services, offering flexible and versatile application in a wide range of locations.

Dry type transformer

ScZB10

Dry type transformer

Dry-type transformers are mainly used in fire-proof and explosion-proof locations in cities and large industrial and mining areas, such as high-rise buildings, underground buildings, airports, transportation hubs, communication and information centers, important municipal facilities, densely populated urban areas, and commercial centers, in 6～35kV power distribution systems.

Grounding transformer

DKSC

Grounding transformer

The function of a grounding transformer is to provide a neutral point when the system is connected in a delta (△) or Y configuration where the neutral point cannot be brought out. This neutral point is used to connect an arc suppression coil or resistor. This type of transformer uses a Z-connection (or zigzag connection). The difference from an ordinary transformer is that each phase winding is divided into two groups and wound in opposite directions on the same magnetic pole. The advantage of this connection is that the zero-sequence flux can flow along the magnetic pole, while in an ordinary transformer, the zero-sequence flux flows along the leakage magnetic path. Therefore, the zero-sequence impedance of a Z-type grounding transformer is very small (around 10Ω), while that of an ordinary transformer is much larger.

Filter air core reactor

lKGKl

Filter air core reactor

The filter reactor and filter capacitor are connected in series to form a resonant circuit, which resonates at a specified frequency point to filter out specified high-order harmonics. It can also achieve reactive power compensation for the power system and limit the inrush current when the capacitor bank is connected to the grid. Dimensions can be customized according to user requirements.
