Four kinds of network, four different reasons an insulator gets chosen. The catalogue is the same; the argument for each part is not.

Transmission lines are built once and maintained for thirty years, so the insulator decision is really a maintenance decision taken decades in advance.

A distribution network is thousands of identical decisions repeated across a service area. The unit price matters, but the failure rate multiplied by the truck roll matters more.

Rural electrification is a logistics problem wearing an engineering hat. The parts are small and cheap, the quantities are enormous, and the programme stalls when a store cannot issue the right size.

Pollution does not break an insulator, it shortens the path across it. Salt, cement dust and fertiliser all do the same thing differently, and the selection has to start from the site, not the catalogue.

Transmission, distribution, rural electrification or a polluted coastal line. Send the site conditions and we will start from those.
