TED Buriable transformer |
The TED transformers are intended to supply long distance public lighting networks from Medium Voltage networks (MV 1 to 6.9 kV) by stepping-down the voltage to Low Voltage (LV 120 to 415 V). |
The TED transformers are standardised products ready for use. They comprise of not only the MV/LV transformer, but also the MV and LV protection devices as well as the epoxy resin enclosure for the MV primary and LV secondary circuits.
Standard Features
The epoxy resin enclosure provides an IP 68 class protection (watertight under 1 meter of water), which gives the TED a very long lifetime even in humid and hostile environments.
The TED offers a total protection in order to simplify installation and maintenance procedures, which is achieved by integrating the MV fuses and using plug-in connectors for the LV circuit breaker.
The power rating range is from 400 VA to 32 kVA (other specifications on request).
Power ratings from 50 to 100 kVA can be offered with a metallic enclosure that is epoxy resin painted.
