Description
A wide range of electrical grade insulation crepe kraft paper can be offered.These papers are widely appreciated by our clients as the PH value of the paper remains intact, a little more towards acidic as preferred in transformer insulation.
Features:
1. Width: 20-870mm.
2. Thickness: 0.35mm(base paper thickness: 0.05mm), 0.48mm(base paper thickness: 0.075mm) and 0.80mm(base paper thickness: 0.130mm)
3. Different width can be provided accordingly.
Advantages:
1. To manufacture these papers, we make use of fibers of pure wood pulp that ensure that papers are in compliance with international quality standards.
2. These papers are chemically neutral with low ash,chloride and sulphide content.
Application:
The crepe paper is used as insulation in manufacture of oil transformers, current transformers of types IMB,CT & CVT as leads and shields.
