mini hdmi cable and introduce some of the problems

Electrical equipment installation, always encounter the need for short cables single cable. Electrical engineering installation, sometimes with three core high voltage cable, stripped the skin, and then WISDOM Mini HDMI cable  stripped ladle armored cable, take three cores for single-core cables. Even single-core cable insulation resistance World to meet the requirements, if installed from outside the core metal components close, will also appear on the structure discharge phenomena, wet weather in the spring is more obvious, this phenomenon would endanger equipment and personal safety. Why insulation standards will appear in the discharge phenomenon? We electromagnetic theory, we can see three core cable distributed capacitance three phase, is surrounded by the shield contact, there is no external electric field, there is only the WISDOM fiber optic cable  electric field. Energy transfer can only be carried out in-house, will not be disclosed. Unshielded high-voltage insulated wire distributed capacitance is more complex, but from the recent grounding wire capacitance largest body most likely to produce a discharge.
