Logistics and network
Supplying Jammu and Kashmir.
Deliveries across Jammu and Kashmir start at about 500 km by road, which puts the nearer cities (Kathua, Jammu, Srinagar) within 3 days of dispatch. The state's demand centres on Jammu Bari Brahmana and Samba industrial estates, Srinagar, Kathua, hydro projects.
Distribution in Jammu and Kashmir is handled by JPDCL and KPDCL; JKPTCL runs the transmission network. Programmes now in execution include RDSS, J&K distribution strengthening, and each is tendered against a technical specification that we quote and manufacture to.
The product
A solar transformer is not a distribution transformer with a different label.
An inverter feeds the transformer a non-sinusoidal current with significant harmonic content, and it does so on a duty cycle that is de-energised for roughly half the year. Both facts change the design.
Harmonic currents drive eddy-current heating in the windings that a standard design does not allow for, so conductors are transposed and the core flux density is de-rated to leave headroom. The overnight de-energised period means no-load loss dominates lifetime energy cost far more than it does on a distribution feeder — which is why the low-no-load-loss design is worth paying for here and not always elsewhere.
