heat shrink tubing/tubes were developed in the USA in '50. for the aerospace industry.The wide range of applications and ease of use make heat shrink tubing applicable wherever it is necessary to protect, seal, insulate or connect many cables, wires or braids made of synthetic or natural materials.
Some types of heat shrink tubing may include an adhesive layer that helps bond the tube to the underlying material to form a waterproof seal, or an electrically conductive layer that provides an electrical connection between the two ends of the wire without having to solder them.
Use of heat shrink sleeves in photovoltaicsHeat shrink sleeves are used in:
- sealing cable/wire connections against water and dust
- insulating connections cables/wires
- sealing corrugated pipe joints
- marking cables/wires (using different colors)
- bundling multiple wires
- insulation of cable connections with ring terminals
The material for the production of heat shrink tubing is modified, cross-linked polyethylene.Cross-linked polyethylene has the so-called"shape memory".Thanks to this, a heat-shrinkable tube/sleeve heated on a rigid element takes its shape and clamps on it. heat shrink tubing is marked with a shrink factor or a measure of how small it becomes after shrinking compared to its original size.For example, the skurczu 2:1 wskazuje ratio for tubes whose diameter is twice as large as the shrinkage diameter.
heat shrink tubing uses hot air blowers, propane-butane torches (soft yellow flame) or other heat sources capable of heating the fixture above %p4 /%The surface on which the tube is to be shrunk must be cleaned and degreased, and the shrinking process should start from the center of the tube.
Technical data- Inside diameter before shrinkage - 12,7 mm
- Inside diameter after shrinkage - 6,4 mm
- Length - 1 m
