Since 1976, the company has been developing, manufacturing and supplying its products to mining enterprises, including 30 years on the market of excavator electric drives. Today's production achievements have become possible due to the highly qualified engineering and technical personnel with extensive experience in the development and operation of all types of excavators. The company conducts scientific research, design search and industrial implementation of new developments. Considering the need for new technologies, we pay great attention to modernization of electrical equipment of excavators of current Russian models.
Main production
The range of products includes a wide range of electrical equipment designed to control the electric drives of quarry excavators:
- Low-voltage switchgears (LVS) for all types of excavators produced by LLC "IZ-KARTEKS named after P.G. Korobkov" and PA "Uralmashzavod" from EKG-4,6 to EKG-20, and also dragline excavators of ESH series according to the systems:
- active rectifier – frequency converter – asynchronous motor (AR-FC-AM) based on powerful IGBT transistors;
- transistor converter – motor on system (ТrP-D);
- thyristor converter – motor (TP-D);
- thyristor exciter-generator-motor system (TV-G-D).
- PAEKT transmitting complexes, which are designed for powering and controlling excavator stroke motors from EKG-4,6 to EKG-20, as well as SBSH.
- High-voltage equipment:
- Complete switchgears (switchgear) with high-voltage protection unit.
- Switching points (KRU-6RPP1) with high-voltage protection unit.
- Crushing units protection device of a new generation (UZD-M2).
- Thyristor monoblock excavator converters (PTEM).
- Devices of protective shutdown (PDT).
The company has certified equipment for testing high voltage products with voltages over 1000 V. All produced low-voltage switchgears are factory tested for real load (sold to the consumer with 97-98% availability). Although these tests are financed from our own funds, we are ready to incur these costs in order to deliver proven, high-quality and reliable products to the consumer.
