Product Description

H525 Insulation and Water Resistant Self-curing Protection Pad

Data Sheet
Product Description
H525 insulation and water resistant* self-curing protection pad has been specifically developed as an easily applied and ambient temperature curable pad for protection of 10kV bare overhead line.
H525 provides vacuum package, which could be easily and quickly applied manually without tools after opening package.
H525 before curing combines suitable initial strength, excellent self-fusion and outstanding property to follow irregular surface.
H525 after curing delivers good insulation, water resistance*, outstanding flexibility, excellent UV resistance and other multiple performances for protection.
Product Features

• Ambient temperature curing
• Convenient to use
• Good insulation
• Excellent UV resistance
• Outstanding flexibility
• Good heating resistance
• Good flame retardant performance

General Application Steps

1. 1. Remove oil, grease and loosely adhering deposits
   2. Recommend to remove metal burr by abrasion
   3. Apply H525
   4. Overlap between two pieces of H525
   5. Repair any defects
   6. Allow to cure
