The need for UL certification for energy storage power harnesses?

ONE. What are the common failures of energy storage power harness?
Energy storage power harnesses always fail for a variety of reasons during operation. Common failures include poor contact of the plug, short circuit between wires, broken circuit, hitch and so on. So, what are the reasons for energy storage power harness failure?
1, natural aging or damage, energy storage power harness harness use time exceeds the use period, the insulation of the energy storage harness slowly began to crack, the mechanical strength began to decline, over time it is easy to lead to short circuits between the wires and wires, disconnections, overrides and other failures. Photovoltaic energy storage connector wire harness use more than the use of the period, so that the wire aging, insulation layer rupture, mechanical strength decreased significantly, resulting in short circuits between the wires, disconnection, hitch, etc., resulting in wire harness burned out.
2, energy storage harness terminal oxidation, when the energy storage harness terminal is completely oxidized, or has been deformed, will also cause poor contact or short circuit of the energy storage harness, so that the energy storage harness failure. New energy storage wiring harness load source is the wiring harness service object, usually refers to the user equipment; broadly speaking, the upper level of equipment is the next level of equipment load source. In telephone communications, the load source is also known as the source of words, the number of service equipment contained in the harness, known as the capacity of the harness, Figure 1 is a schematic diagram of the harness.
3, electrical equipment failure, there is also a situation because the electrical equipment overload operation, short circuit, which leads to energy storage harness failure.
4, man-made reasons, A after a cause of failure is the cause of improper human operation, such as energy storage harness installation location is not reasonable, the energy storage harness and electrical equipment wiring error, maintenance damage to the energy storage harness components and so on.
