- Today, we will introduce how to choose a heat shrinkable busbar tube based on the specifications of the copper busbar. Overly large busbar sleeves are time-consuming to shrink and expensive, and too small busbar sleeves cannot fit properly. Therefore, choosing the appropriate size and specifications is very important.
Firstly, we need to choose the matching voltage level. Our manufacturer's busbar bushings are generally divided into 1KV and 10KV; Three types of 35KV. Heat shrink tubing is classified according to its diameter, while the specifications for copper bars in switchgear are generally rectangular in width x thickness. Some customers are confused about how to choose. It's actually very simple. According to the conversion formula, the circumference of the copper bar/3.14=diameter. After calculating the diameter of the copper bar, you just need to choose a heat shrink tube for the busbar that is slightly larger than the diameter. Welcome to call us anytime for consultation.
