POROFOL ® CR 2578 consists of highly absorbent mica paper based on uncalcined muscovite and polyimide-film (e.g. KAPTON®¹ CR)
POROFOL ® CR 2578 is a flexible tape suitable for hand and machine taping. In spite of the polyimide-film a great number of layers can be impregnated in a short time due to the high porosity of the mica paper. Mechanical and electrical properties of the final insulation mostly depend on the impregnating resin used. In combination with high thermal classification VPI-resins (e.g. silicone resins) the outstanding thermal performance of the polyimide-film in POROFOL ® CR 2578 can be enabled. The polyimide-film as carrier ensures an increased partial discharge resistance.
POROFOL ® CR 2578 is used in VPI-systems for continuous insulation of coils and bars of low and high voltage machines a well as interlayer insulation in VPI-dry type transformers.

Wilec has embarked on an intensive modernisation and recapitalisation program. The program has been rolled out in both the Olifantsfontein and City Deep manufacturing facilities. The state of the art machines that have been installed have already produced improved quality, control and efficiencies.
In addition to this, product diversification and market substitution have also been factored into the procurement and planning of the equipment purchased.
Extensive training has been rolled out to our manufacturing teams such that both man and machine are equipped to deliver products that exceed specification and customer demands.
