Oil-immersed power transformers are electrical appliances that use insulating oil as the insulating medium and are composed of cores, coils, voltage regulator switches, oil tanks, etc.to change voltage and transmit AC power.It has the characteristics of small size and strong weather resistance. Applicable to power systems, industrial and mining enterprises, transportation, post &telecommunications and scientific research bureaus, etc.It is divided into flat stacked core series, three-dimensional…
The intelligent assembly line test system is divided into insulation resistance, transformation ratio, DC resistance low voltage test stations; no-load, load, power frequency, induction, high voltage test stations; each logistics line can realize insulation resistance, transformation ratio, DC resistance, no-load, load, induction withstand voltage, power frequency withstand voltage test. The low voltage test station and the high voltage test station do not affect each other and run at the same t…
An Isolation transformer is the best way to establish a new neutral-ground bond,in order to correct common mode and other grounding problems.A transformer can provide conversion of a Delta system(3 wire)to a Wye connected (4 wire) system.The addition of an electrostatic shield adds further protection from some high frequency impulses and noise that might other wise pass through the transformer via the inter-winding capacitance.A shielded isolation transformer provides excellent protection from a…
The core of 110kV power transformers is made of high-quality silicon-steel sheets,and laminated by steps.It is advantageous in low loss,low noise, and high short-circuit withstand capacity,etc.Now it is wildly used in power station, power plant,and gets high praise from them.SZ11-63000/110 transformers have passed a complete set of National testsand the short-circuit withstand capacity test.

Product Introduction:
The YZFN-10 (20) series load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz and a rated voltage of 20kV. It uses transformer oil as the insulation and arc-extinguishing medium, and the operating mechanism is a spring energy storage device. With three-phase linkage, it can accurately and quickly make or break the rated load current. It serves as a control and protection device for industrial and civilian electrical energy in ring-main pow…
Two-position oil-immersed load switch:
The FYB-24 type two-position oil-immersed load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz and a rated voltage of 24kV. It is a load switch specially designed and manufactured by our company for the increased voltage class of domestic integrated transformers.
The BYF1-40.5 type two-position oil-immersed load switch is suitable for integrated transformers with AC frequencies of 50Hz and 60Hz, and a rated voltage of 35k…
This Insulation Protective Cap is an accessory product to other 15kV 200A products with loadbreak interfaces (bushing inserts, loadbreak junctions, feed thru inserts, etc.).It is designed to physically seal and electrically insulate loadbreak bushing interfaces. When installed on a loadbreak bushing interface, and properly grounded using the attached drain wire, the Loadbreak Insulation Protective Cap provides a submersible, fully shielded insulated cap for energized bushings. The Loadbreak Insu…
The Bushing Insert threads onto a standard 200A bushing well.The combination of the bushing well and bushing insert perform the same function as a one piece integral loadbreak bushing, while providing the flexibility to change the bushing insert in the field, without taking the transformer or other apparatus out of service. The bushing insert and loadbreak elbows are the primary components in all ANSI/IEEE loadbreak connections.
The Bushing Insert incorporates an all copper current path.This pro…
The four-position loadbreak switch
is used in underground residential
applications with loop feed, and in three-phase commercial industrial
installations where the ability to use an alternative source of power is
necessary. They can also be used to close or open the power source.
The switch uses a manually charged over-toggle stored spring
assembly to operate , which is independent of operation speed.
The silver plated copper blades are securely keyed between the
vented rotor halves which ensure…
