ENPAY uses the newest, computerized version of GEORG Cut-to-Length Machines in order to produce step lap laminations. Advantages of cutting in step lap are:
• reduction in iron losses
• lower noise level
• time saving in assembly.

Several GEORG Step-Lap Cutting Machines are in operation. Cores with band with up to 1 meter can be produced.

ENPAY has different sizes and types of stacking tables in order to produce complete flat stacked laminations, and Step-Lap transformer cores. All necessary insulation parts from transformer board or plywood for yoke clamping and winding supports are manufactured according to customer specifications and drawings if available. Reel frames are also produced for dry type transformers as per the customer requirements. The cores are glued and varnished according to the technical requirements (core gluing varnish for all transformers). The legs are bandaged if desired. The customer receives complete cores with insulation parts. The sheets may also be delivered as cut-to-length laminations. The cores are built on modern core stacking tables. Stacking on guiding bolts and most accurate setting of the leg supports on center distance enables to keep the geometrical dimension on leads to an absolute minimization of the air gaps. The completely clamped core is then swung into vertical position 90° by means of a hydraulically operated table platform, resulting in a tension-free-up-tilting. A pre-measurement of the core losses guarantees the required no-load losses.

Up to 1000 mm width for largest power transformers.

If the core weight is over 50 tons, the limbs and the yokes will be packed on separate palettes.

Ready stacked and fixed limbs can be produced according to customer's design in order to save cost for assemblies.
