What is yellow-green (earth color scheme) heat shrink tubing?
What is yellow-green heat shrink tubing? Types, uses, ratios, benefits of use, and examples of use
What is yellow-green heat shrink tubing anyway?
Heat shrink tubing, characterized by its yellow and green striped pattern, is an insulating protective material that is widely used to identify earth wires (ground wires) .
To ensure the safety of electrical and electronic equipment, it is important to "clearly identify the earth wire." International standards such as CE marking and IEC (International Electrotechnical Commission) stipulate that the earth wire should have a "yellow-green stripe."
Heat shrink tubing is a very effective way to add color identification.
Yellow-green color ratio and standard relationship
CE marking and IEC 60445 color scheme specifications
-
It is specified that the earth wire (PE: Protective Earth) should be identified by a "green/yellow (green/yellow stripe)" color.
-
Regarding ratios:
-
The proportion of either yellow or green must not be less than 30%
- The recommended ratio is approximately 50:50 with an even color scheme.
-
Differences in manufacturing methods and quality
The yellow and green stripes are formed through the following process:
-
Co-extrusion (two-color simultaneous molding) : Little color mismatch and high precision. Cost is somewhat high.
-
Printing method : One color is printed on the base. It is prone to misalignment and fading, but is low cost.
-
Laminated layer : Two layers of film are stacked, but there is a risk of the layers peeling off.
When quality is a priority, co-extruded tubing is ideal.
Our earthing heat shrink tubing is manufactured using a co-extrusion process.
Actual usage scenarios
| Usage scene | Usage examples and purposes |
|---|---|
| Control panel modification and repair | Add earth identification tubes to existing wiring as a retrofit |
| CE compliance measures for equipment for overseas markets | Regular electric wires can be color coded to facilitate CE compliance |
| Construction machinery and vehicle harnesses | Vibration and weather resistance while ensuring visibility |
| Strengthening safety signs on equipment | Yellow and green stripes raise safety awareness and prevent accidents |
