NON SHRINKABLE INSULATION TAPE
Gala Non Shrinkable Insulation Tape is an EPR based insulation tape
possessing excellent electrical, chemical and physical properties. it maintains a tight
insulation built up without any voids giving good electrical stability and resistance to
moisture penetration. Compatible with most commonly used Cable Jackets i.e. XLPE, PVC,
PILC or Rubber Sheathed Cable.

Features & Benefits:
- The tape has the property of cold flow, thereby when applied with 50%
overlap, different layers, sticks with each other resulting into formation
of void free insulation.
- Excellent resistance moisture, contamination and adverse environmental
conditions.
- Excellent UV stabilized & weather resistant.
- High heat dissipation helps to keep the conductor cooler.
- Provides protection to the conductor material againstcorrosive elements
present in the environment.
- Standard Color: Black
Installation Instructions:
- Keep open end of the tape on the start position of the cable to be insulated
and then stretch the tape so as to reduce the width to 2/3 of its original
width and then start wrapping 2/3 width tape with 50% overlap continuously
around the cable till no portion is left uninsulated. Then repeat the taping
process till the desired insulation & thickness is achieved.
- The tape should be applied in successive half lapped, level wound layers
until desired build up is reached. To eliminate voids in critical areas,
highly elongate the tape. Stretch the tape in these critical area just short
of its breaking point. In less critical area, less elongation is sufficient.
Stretch 3/4 of its original width in less critical area.
- Always attempt to half lap to produce a uniform build up.
Recommendations:
- Care should be taken to avoid direct contact betweenthe tape and petroleum
type solvents and oils. Oils may affect the electrical properties of the
tape.
- The rolls should be stored flat on their cut edges in theoriginal
packaging. The product must be protected dust, heat, moisture, direct
sunlight and solvent fumes. Storage temperature between +100C and +300C.
Under these conditions, the storage life of the tape in a temperature
climate will be at least five years.
