- Description: PT. Gajah Tunggal Tbk. is the largest tire manufacturer in Southeast Asia, the company produces and distributes tires for passenger car, SUV’s, commercial, off-road, industrial vehicles and motorcycles.
They also manufacture and distribute other rubber related products such as synthetic rubber, tire cords, inner tube, flap, o-ring and more.
PT. Gajah Tunggal built a new plant in Tangerang, Banten (West of Java) called TBR2000, equipped with several robotic machines for welding application.
The Indonesian distributor of LOVATO Electric, PT Maxindo, has been involved in the project for the supply of components for the manufacturing of 7 dynamic switching capacitor banks. LOVATO Electric components have been used for the manufacturing of the following capacitor banks: 6 pcs capacitor banks 3080kVar at 525V, 1 pc capacitor bank 2400kVar at 525V.
The capacitor banks have been configured taking advantage of the master-slave functionality of DCRG8: for the 6 banks of 3080kVar each, the installation was performed with 1 master DCRG8 and 2 slaves DCRG8 controller, communicating each others via RS485.
In such configuration, it has been possible controlling the total power of 3080kVar on each bank.
Each Master controller of every capacitor bank has been equped with EXP1013 ethernet expansion module in order to allow a remote monitoring of the whole installation using the existing ethernet network available in the factory.
