BPEG reactor is a dry type air core construction with multi-layer of windings paralleled. Each winding consists of a small-section parallel-insulated aluminum wires. The whole reactor is integrated by epoxy fiberglass hardened in the drying store and the leading-out ends of each winding layer are welded to the upper and lower spider arms.
The reactor is cooled with neutral air, the surface of the reactor is painted with resist aging, ultraviolet-proof insulation coatings. All these features make BPEG reactors have many advantages, such as low loss, high strength, low noise, being easy to mount and simple for maintenance. Their life expectancy is more than 30 years. In addition to the normal fixed inductance type of coil, BPEG also manufactures adjustable reactors including multi-tapped adjustable ones and continuous adjustable ones. Generally, the variation in inductance of the coil is at least 5%.
The application standards are IEEE/ANSI, GB10229, IEC289-88. Other standards can be requested as BPEG Reactors have a wide selection of reactors. Types of them include: Shunt Reactor, Thyristor Controlled Shunt Reactor (TCR), Series Reactor, Special Series Reactor used in electric railway, Current-limiting Reactor, Filter Reactor, Smoothing Reactor, Test Lab Reactor, Damping Reactor, Splitting Reactor, Neutral-Grounding Current-limiting Reactor, Starting Reactor, Load-sharing Reactor, Lighting Coils, etc.
-
Shunt Reactors
| Shunt reactors are parallel connected with the transformer tertiary winding in 220kV or 500kV Substation. They are used to compensate for the capacitive VAR reactance of the underground cable in the transmission line of long distance and low load. |  |
-
TCR Shunt Reactors
| Thyristor Controlled Shunt Reactors (TCR) are used in static VAR compensating devices and can dynamically change the VAR compensating power and keep the voltage stable. |  |
-
Series Reactors
| Series reactors are series connected with a VAR compensating shunt capacitor bank. They are used to restrain harmonic voltages, reduce distortion of system voltage and limit in rush current when the capacitor circuit is put into network for operation. |  |
-
Filter Reactors
| Filter reactors are series connected with a filter capacitor bank to form resonant circuit, which can filter specified harmonic currents. |  |
-
Current-Limiting Reactors
| Current-limiting reactors are series connected with power system (bus, line and load) They can reduce the short circuit current to allowable level for other equipment. |  |
