Electrical insulating flexible crepe paper tube

Electrical insulating flexible crepe paper tube

Made of electrical grade insulation crepe kraft paper.

Features:

1.Standard length is 1000mm, 1500mm, 1800mm, 2000mm.                

2.Different inner diameter and outer diameter can be offered by customers' requirement.

Advantage:

They can be bent under extreme conditions without collapsing.

Application:

1. Used as sleeves for interconnection of terminals.

2.Used in the oil-type transformers with higher rate of absorption of oil to ensure higher dielectric strength compared to conventional SRBP tubes.
