3M™ Self-fusing Electrical Tape J20
Instructions for use
When using 3M Self-fusing Electrical Tape J20 continuous semi-overlapping wrapping is appropriate. After stretching the width of the original 3/4, to ensure a better model and insulation effect. When applied, pay attention to the voltage level: 10KV and below can be used for cable insulation protection, 1KV and below can be used for main insulation recovery.
