Logistics and network
Supplying Andhra Pradesh.
Deliveries across Andhra Pradesh start at about 1790 km by road, which puts the nearer cities (Rajahmundry, Visakhapatnam, Vijayawada) within 7 days of dispatch. The state's demand centres on Visakhapatnam steel and port, Kakinada and Krishnapatnam ports, Sri City and Nellore industrial corridors, Anantapur and Kurnool solar parks.
Distribution in Andhra Pradesh is handled by APEPDCL, APSPDCL and APCPDCL; APTRANSCO runs the transmission network. Programmes now in execution include RDSS, Kuppam and Anantapur solar parks, and each is tendered against a technical specification that we quote and manufacture to.
A servo stabilizer holds the output voltage steady by continuously varying a motorised variac, rather than switching between fixed taps. That gives smooth correction with no waveform distortion and no switching transient — which matters when the load is a CNC machine, a medical imaging system or a process line rather than a lighting circuit.
Three-phase units are built as single-variac (all phases corrected together) or three-variac (each phase independently). Specify three-variac where the incoming supply is unbalanced, as most Indian industrial feeders are.
