I. Panel

As in the present scenario the steel plant are getting more and more production and quality oriented and this requires lot of heavy and sophisticated type of electrical installation. Hence forth as we have expertise in electrical field we also commission electrical panel and manufacture it. We manufacture all kinds of electrical and control panels required for automation of steel production installations. We have been in panel manufacturing business for near about 15 years and we have manufactured 61 MVA of distribution and control panels and 7000 KVAR APFC panels. Following listed are panels we deal in:

Power Control Centre (PCC)

Electrical power for industrial requirements is continuously on the rise and there is increasing need for power control panels with all round protection (like circuit breaker with microprocessor or thermal trip), high reliability and longer life. Unimeec has always endeavored to provide power control centre with incorporation of all relevant Indian and International standards to provide best products. Following are salient points of our PCC Panels.

  • Modular Construction (separate compartment for every power incoming and outgoing).

  • Short Circuit rating of up to 65kA.

  • Busbar Rating of up to 6000A.

  • All panels with ingress protection of IP-42.

  • Operating temperature 0-55C.

  • Cable entry: Bottom Entry or Top Entry.

  • Easy operation and Maintenance.

Electrical Bus-duct System

Electrical Bus-duct system has become very important part of today’s electrical installation where the requirements cannot be met by hard wired system. In systems where installation has to be done fast, have limited space or has to be aesthetically pleasing, bus-duct systems have been used. Bus-duct system has also been used in systems where there is a very large current requirement. Unimeec has installed bus-duct systems in all kinds of applications, like for e.g. Induction Furnaces, PCC Panels, Large rating L. T. motors etc. We have installed systems both in Aluminum and Copper material. Following are few salient features of our Bus-duct systems.

  • Bus-duct system design is customized.

  • Short Circuit rating of up to 50kA@3 sec.

  • Voltage Insulation rating of up-to 11 kV.

  • Bus-duct System Rating of up to 35000A for a 12 pulse system.

  • All bus-duct with ingress protection of IP-42 for indoor installations and IP 56 for Out-door installation

  • Forced air cooling for all Bus-duct system up-to 30000 Ampere.

  • Operating temperature 0-55C.

  • Future Development: Water Cooled Bus-duct system for rating above 30000 Ampere up-to 60000 Ampere systems.

Motor Control Centre (MCC)

For all industrial applications for driving loads with electrical power, electrical motor (especially induction motor control) are used extensively. In order to start, stop and control electric motors, there is requirement of starter and relevant control circuits to control these motor starters. Unimeec specializes in design of these starters and we always use genuine electrical components like circuit breakers, contactors, Over-load relays, etc. Following are few focal points for our designed MCCs.

  • Modular design (for long life and easy access).

  • Short circuit rating of up to 50kA.

  • All panels with ingress protection of IP-42.

  • Operating temperature 0-60C.

  • Construction: Indoor/Outdoor, single-front/double-front type.

  • Cable entry: Bottom Entry or Top Entry.

Automatic Power Factor Control (APFC) Panel

With increase in demand for electrical motors in industry, there is growing demand for efficient power factor correction solutions to get the power factor to unity. As the electrical load continuously vary in industrial environment, adding a single capacitor bank to compensate this varying load may lead to following:

  • Over compensation (more KVAR than required) which will result in leading power factor, and this reduces p.f. and thus avoidable. Also leading power factor is un-healthy for capacitors and system itself.

  • Power loss in capacitors in case of over compensation.

Automatic power factor controls avoids all above problems by step by step switching on and off the capacitors as the requirement arise. The capacitor bank is divided into such combination that a continuous step in KVAR can be used. For example capacitor bank of 5, 10, 20, 40 KVAR can be used in combination to get step of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75 KVAR to get a very efficient control of power factor. Unimeec provides best possible combination of power factor control to get maximum out of capacitor banks. Following are few advantage of use of APFC panel:

  • Efficient use of capacitors leading to elongated life of capacitors.

  • Avoid over compensation and under compensation.

  • Maintain unity power factor thus effective use of available power and avoid penalty for poor power factor.

D.C. and A.C Drives with SCADA system.

As the A.C. and D.C. motors are more and more used for variable speed applications to precisely control the speed of motor, A.C and D.C. drives are progressively used for these applications. SCADA (Supervisory Control and Data Acquisition) application is used to provide human machine interface (HMI) to operator to observe various system parameters and also feed various control parameters to control the drive. SCADA system also consists of PLC (Programmable Logic Controller) which calculates the actual control parameters from data fed by operator through HMI.

Special Application Logic Panels

We bring forth Special Purpose Logic Control Panels, which find wide application in automating numerous electromechanical processes such as lighting fixtures or controlling the functioning of a machine. We have designed the products in such a way that these can perform even in tough & extended temperature conditions. These vibrant and impact resistant products are made using excellent quality raw material, sourced from trustworthy vendors of the market. We also expertise in customized electric or drive panels for special or specific applications like in steel production, cement industries, agglomerate marble industries or any other industries after understanding the detail requirements of the customer.

II. Electrical Installations and Equipments

We have been in the field of commissioning of electrical installations like switchyards up to 132 KV for the last 15 years. While commissioning of high voltage installations we always endeavor to conform to all the required Indian and International Standards in order to provide best possible solutions. We also manufacture various equipments like water resistance starter for slip ring motors. Following are few of our portfolios:

Substation Installation

With increase in electrical power requirement in every industrial sector, there has been corresponding rise in demand for substation of 11kV for power requirement up to 4MVA and for 66kV for power requirement above 4MVA. Substation installation being a complex task requires attention to details in fields of civil, electrical and mechanical. Unimeec executes the substation installation on turnkey basis with the help of engineering experts of all relevant fields. We consider many aspects while designing the substations. Following are but a few:

  • Electrical and mechanical design requirements of various electrical components like power transformers, isolators, current transformers, circuit breakers, earthing, battery banks, etc. conforming to various IEC/Indian standards.

  • Civil design requirements for foundations of different substation components and their proper placements.

Starters For Large Induction Motors

Induction motor by its inherent characteristics draw large value of current at its starting, which becomes a problem in case of large motors as this value of starting current is 4 -5 times of rated current that is drawn by motor in normal conditions. In order to control this starting current for motor starters are used. These starters can be of many types like water resistance starter for slip ring induction motors which controls the current flowing in the rotor by introducing resistance in rotor electrical circuit, and slowly cutting the resistance out as the motor speeds up. Similarly soft starters are used for smooth start-up of induction motor and also avoid oversized mechanical and electrical components to cater for the power surge on start up. Products offered are:

  • Water resistance starter for up to 2000 HP Slip ring induction motor

  • Soft Starters for Induction motor.
