We Will Never Force A Solution. We Will Engineer The Answer.

We continually work to create products with higher efficiencies and better value. 

Each year we make substantial investments in the research & development of new products and manufacturing techniques.

We regularly innovate on behalf of our customers, collaborating with them to find solutions to their specific challenges.

Hainan Jinpan Intelligent Technology Co., Ltd. (hereinafter referred to as "JST"), founded in 1997 and located in Haikou City, Hainan Province, China, is a private enterprise specializing in the design and manufacture of transformers. It is progressiveness in the manufacturing technology of distribution transformers, keeping pace with the international level.

We have four R&D and manufacturing bases in Haikou, Wuhan, Shanghai, and Guilin, as well as sales and production bases in the United States and Mexico. 

JST was listed on NASDAQ in 1998 and on the A-share Science and Technology Innovation Board in 2021. 

At present, all JST factories have upgraded to Industry 4.0 digital chemical plants and meet the VDI4499 standard of the German Association of Engineers, and have passed the certification of TUV NORD in Germany.

JST transformer products have successively obtained a series of authoritative certifications such as KEMA testing in the Netherlands, UL certification in the United States, EU CE, DNV GL certification by the Norwegian German Classification Society, CSA certification in Canada, BV certification by the French Classification Society, China Classification Society certification, energy-saving product certification, and provide transformer technical consulting and solution services that meet GB, IEC, IEEE, NEMA, CSA, JEC and other standards.

The company has developed the "Digital Factory Management Manual", "Digital Factory Operation Management 

Procedure", "Digital Factory Preparation Management Control Procedure", "System Architecture Creation 

Management Procedure", "Data and Data Model Management Control Procedure", "Digital Factory 

Implementation Control Procedure", "Digital Factory Overall Architecture", and "Digital R&D Plan Specification" 

in accordance with the VDI4499 Digital Factory Construction Standard of the German Association of Engineers 

The three-level quality management documents, including the digital production plan manual, digital 

management plan manual, digital marketing and service plan manual, have established a management system 

for factory construction planning, production automation, material automation, information flow automation, 

and digital factory construction.

JST offers Iron Core Reactors that are used in a wide variety of applications. The most typical applications are to supply inductance to mitigate current and voltage harmonics with non-linear loads. Reactors are used either alone or with capacitors and/or resistors in filter circuits.

Iron Core reactors, unlike Air Core reactors, have a core which saturates once design current levels are exceeded. Iron core reactors are typically not used in current limiting applications.

  Types & Applications of Iron Core Reactors 
★DC Link Choke ★
Filters and controls DC bus voltage and current in a variable frequency drives (VFD) and other rectifier circuits. DC Link Chokes smooth the ripple current flow to the VFD and help reduce AC input line current harmonic distortion while absorbing DC bus voltage.

★Filter Reactors★
Used as a component of a filter to reduce harmonic levels in electrical power systems. Filter Reactors are used in a variety of configurations and are usually coupled with capacitors and/or resistors.

★Interphase Reactors★
When paralleling two rectifier bridges an Interphase Reactor provides balanced system operation when both rectifiers are conducting by providing a high impedance between the two converters and low impedance to the load.

★De-Tuning Reactors★
These iron core reactors are designed to limit the amount of harmonic current from non-linear loads on the reactor to the fixed impedance loads on components such as capacitors, transformers and cabling. De-Tuning reactors also mitigate voltage amplitude from increasing in circuits with non-linear loads.

★Power Factor Correction Reactors★
Essentially these are de-tuning reactors specifically for use with power factor correction capacitors. They limit the amount of current present on the capacitors from harmonics to prevent heat and high current stresses to improve the capacitor's operating life.

★Motor Starting Reactors★
A series reactor designed to limit a motor's inrush current during start-up by reducing the input voltage to the motor. Motor Starting Reactors have a short duty cycle and are switched out of the circuit once the motor has reached it's rated speed. These are typically three phase reactors but less common schemes will use a reactor on only one phase or use an Air Core reactor.

★Line and Load Reactors★
Line Reactors are used at the input of the VFD to mitigate harmonics and nuisance tripping as well as to reduce voltage line notches. Load reactors are used at the output of the VFD to mitigate the effect of long lead length (reflective wave phenomenon) and to reduce premature motor insulation failure.

★DC Smoothing Reactors★
DC Smoothing Reactors are connected to DC system in series to reduce current ripples. DC Smoothing Reactors reduce harmonics on the DC waveform which in return reduces the losses and improve system stability and performance.
