Interlocking Devices - Electric Control Panel and Liquid Resistance Starter Manufacturer and Exporter | Enterprising Engineers, Bhopal

- Products At A Glance

LIQUID ROTOR RESISTANCES :
THESE ARE USED FOR INSERTING EXTERNAL RESISTANCE IN THE ROTOR - CIRCUIT OF SLIP RING INDUCTION MOTOR AT THE STARTING TO REDUCE STARTING - CURRENT AND INCREASE STARTING - TORQUE. USED IN VARIOUS INDUSTRIES AND INSTALLATIONS LIKE : CEMENT PLANTS, ROLLING MILLS , PUMPING PLANTS, SUGAR MILLS, PAPER PLANTS. WE MANUFACTURE & SUPPLY LIQUID ROTOR RESISTANCES WITH BOTH MOTOR OPERATED OR MANUALLY OPERATED MECHANISM. THESE GIVE STEP - LESS CUTTING OF RESISTANCE AND ARE ECONOMICAL IN COMPARISON TO WIRE WOUND OR GRID - RESISTANCES. WE ALSO MANUFACTURE STATOR - ROTOR PANELS.

LIQUID RESISTANCE CONTROLLERS :
THESE ARE USED FOR SPEED REGULATION OF SLIP-RING INDUCTION MOTORS BY VARYING THE ROTOR RESISTANCE OF THE MOTOR . THESE ARE VERY COMMONLY USED IN CEMENT PLANTS.

GRID ROTOR RESISTANCE & CONTROLLERS :
WE ALSO MANUFACTURE ROTOR RESISTANCE USING STAINLESS STEEL SHEETS (SS PUNCHED GRID RESISTANCE) FOR SIMILAR APPLICATIONS AS LIQUID ROTOR RESISTANCES OR LIQUID CONTROLLERS. 

CASTELL LOCKS INTERLOCKING DEVICES :
DIFFERENT TYPES OF CASTELL LOCKS INTERLOCKING DEVICE TO ENSURE PROPER SEQUENCE OF TWO OR MORE INDEPENDENT OPERATIONS OF ELECTRICAL OR MECHANICAL EQUIPMENTS .THE NEED FOR PROPER SEQUENCE MAY BE SAFETY OF PERSONNEL OR EQUIPMENTS OR IT MAY BE THE REQUIREMENT OF THE PROCESS.

* MECHANICAL INTERLOCKS TYPE DL.
* BOLT LOCKS TYPE K OR L.
* BOLT LOCKS WITH ELECTRICAL SWITCHES.
* DOOR LOCKS TYPE DT1 OR DT2.
* ELECTRICAL INTERLOCKS.

NEUTRAL GROUNDING RESISTORS :
WE MANUFACTURE NEUTRAL GROUNDING RESISTOR (NGR) AS PER CUSTOMER’S SPECIFICATIONS & REQUIREMENTS . NGRs ARE USED IN AC DISTRIBUTION NETWORKS TO RESTRICT EARTH FAULT CURRENT TO A PREDETERMINED LEVEL.RESISTANCE GROUNDING OF TRANSFORMER OR GENERATOR NEUTRAL STAR POINT IS THE MOST EFFECTIVE AND 
PREFERRED METHOD.

AUTO - TRANSFORMER STARTERS :
FULLY AUTOMATIC OR SEMI- AUTOMATIC PUSH - BUTTON OPERATED AUTO - TRANSFORMER STARTERS FOR 415/550 V AC 3 - PHASE SQUIRREL CAGES INDUCTION MOTORS UPTO 150KW/200HP. THESE ARE PROVIDED WITH , 3 - AIR BREAK CONTACTORS, 1-THERMAL OVER - LOAD RELAY, 1 - OIL IMMERSED AUTO - TRANSFORMER STARTER WITH 40%, 60%, 80%, TAPPINGS, 1 - TIMER FOR AUTOMATIC CHANGE - OVER, 1- AMMETER,1-VOLTMETER, START & STOP PUSH - BUTTON. THE STARTER AND AUTO-TRANSFORMER ARE TOTALLY ENCLOSED IN SEPARATE DUST AND VERMIN PROOF SHEET STEEL ENCLOSURE SUITABLE FOR FLOOR MOUNTING. RATIO OF TAPPINGS CAN BE VARIED TO SUIT PARTICULAR APPLICATION.

CONTROL & RELAY PANELS :
WIDE VARIETY FOR DIFFERENT APPLICATIONS LIKE :
1) CONTROL OF H.T. CIRCUIT BREAKERS , PROVIDED WITH 
PROTECTION, INSTRUMENTATION AND CONTROL. THESE ARE 
USED COMMONLY IN H.T. SUB-STATIONS.
2) MACHINE PANELS FOR REMOTE OR LOCAL CONTROL OF 
ELECTRICAL MOTORS.
3) AUTOMATIC MAINS FAILURE (AMF) PANELS FOR D.G.SETS.
4) D.G.SYNCHRONIZING PANELS.
5) AUTOMATIC POWER FACTOR CORRECTION PANELS.
6) CRANE CONTROL PANELS.
7) PLC BASED AUTOMATION PANELS FOR AUTOMATIC CONTROL OF VARIOUS OPERATIONS IN PROCESS INDUSTRIES.
8) AC/ DC DRIVE PANELS FOR VARIABLE SPEED OF VARIOUS MOTORS.
