Based on the most efficient and reliable cast-resin transformer technology of the last 3 decades, the LKE-TCT series of dry-type transformer is available at the voltage ratings of 0.4 kV, 10 kV 20 kV, 35 kV.

- The HV (High Voltage) coil

The transformer’s high voltage coil consists of premium enamel insulated copper wire which are wound with high-precision winding equipment. The coil is casted into epoxy resin via a vacuum casting process which produces epoxy resin insulation with a high degree of reliability. The design methodology for LKE’s transformers is based on a sophisticated mathematical calculation in which the different rates of thermal expansion for both the epoxy resin and the coil were taken into account and due allowances were made to ensure the functinal integrity of the transformer through a broad temperature range.. Therefore LKE’s transformers will reliably operate from -25oC to +155oC.

- The LV (Low Voltage) coil

As the 0.4 kV (LV) coil is expected to carry a load in excess of 500 A, LKE’s transformers uses copper or aluminium foil to construct the LV coil. This application allows the coil to bear higher currents and also avoids the vertical stresses which are existent in spirally winded wire coils. Therefore LKE transformers have a massive short-circuit withstand capability.
