Heat dissipation of power distribution box and charging pile
The air cooling system is currently the most widely used heat dissipation method for charging piles. It is important to consider the various physical attributes of the various pieces of electrical equipment that will be utilized as well as the constraints. Therefore, how to effectively solve the heat dissipation problem of charging piles has become the key to ensuring their long-term stable operation. This heat mainly comes from key. Compared to other power sources, EV charging piles (also known as EV charging stations or EV charging points) generate significantly more heat, making the thermal design of these systems extremely stringent.

Power Communication Optical Cable Fusion Splicing Technology
It is a technique that uses controlled heat to permanently fuse two optical fiber ends together. Unlike mechanical splicing, which relies on alignment sleeves and index-matching gel, this thermal approach creates a continuous glass path between fibers. Fiber optic splicing is the process of joining two fiber optic cables together so that light signals can pass with minimal loss or reflection. Splicing is typically required during cable installation, maintenance, or network expansion. We make fibre optic network technologies, and. Ribbon cable can be spliced more rapidly by using mass fusion splicing technique.
