Products Description
Constructed with high-quality laminated silicon steel cores and windings of high-purity copper or aluminum wire, Line Reactors incorporate high-strength insulating materials, fasteners, and optional protective enclosures. Available in three-phase and single-phase variants, they feature a dry-type design that requires no additional cooling medium. Easily installed, they can be directly connected in series downstream of power circuit breakers and fuses, and upstream of electrical equipment.
The entire product undergoes a rigorous manufacturing process of vacuum impregnation and hot-air curing. The core limbs are equipped with uniform air gaps and fixed using epoxy laminated glass cloth plates to ensure stable air gap operation during runtime. The windings adopt either foil or wire winding technology, and all external components are treated for corrosion protection. Boasting excellent moisture resistance, dust resistance, high-temperature tolerance, and zero electromagnetic pollution, these reactors are capable of adapting to complex industrial environments.
Product Functions
The core functions of the product focus on dual protection. On the one hand, it prevents harmonic currents generated by equipment such as frequency converters and rectifiers from polluting the public power grid, avoiding interference with sensitive equipment in the same power grid. On the other hand, it limits the inrush current at the moment the equipment is switched on, protects front-end components such as the equipment's input rectifier bridge and fuses, and at the same time attenuates voltage spikes on the power grid side, protects sensitive electronic components such as IGBTs inside the equipment, and extends the service life of the overall equipment. In addition, by smoothing the current waveform, it can indirectly improve the system power factor, reduce reactive power loss, and reduce the burden on power supply lines and transformers.

reference indicator
The core reference is 4 key parameters:
-
Rated current: It should be greater than or equal to the rated input current of the equipment.
-
Rated voltage: It should match the grid voltage.
-
Voltage drop percentage: Usually 3%-5% is selected.
The larger the voltage drop percentage, the larger the inductance, and the better the effect of harmonic suppression and inrush current limiting, but the self-loss and volume will also increase. It can be selected comprehensively according to the harmonic suppression requirements and the allowable voltage drop loss. -
In addition, it is also necessary to select the appropriate protection level according to the operating environment.

Q:Is It Normal for the Line Reactor to Generate Heat?
A: Under normal circumstances, the Line Reactor will generate slight heat during operation, which is a normal loss phenomenon and no cause for concern. If severe heat generation or a hot shell occurs, it may be due to improper selection, poor installation ventilation, or product failure, which needs to be inspected and addressed.
Q:Can Harmonics Be Completely Eliminated After Installing a Line Reactor?
A:The Line Reactor mainly suppresses major harmonics such as the 5th and 7th harmonics, which can reduce the total harmonic distortion (THD) to below 8%, meeting the grid power quality standards, but it cannot completely eliminate all harmonics.
Q:Can Line Reactors Be Customized According to Requirements?
A: Yes, we support customization, including rated current, voltage, inductance, voltage drop percentage, installation size, protection level, etc., and can optimize the design according to the customer's specific application scenarios.
