BNC connectors are generally not used in high-voltage transmission scenarios, as they have limited high-voltage resistance capabilities. From a design perspective, BNC connectors are coaxial cable interfaces primarily designed for the transmission of radio frequency (RF) signals and standard video signals, operating at relatively low voltages. The primary structure of these connectors is focused on stable signal transmission, with internal components such as the central pin, insulator, and outer metal shielding layer typically suited for common low-voltage signal environments. Examples include the 12V low-voltage signals transmitted in security surveillance systems or the analog video signals of several dozen volts used in broadcasting and television.

In terms of materials, BNC connectors typically use brass for the housing and plastic for the insulator, without special reinforcement for high-voltage insulation or voltage resistance. If connected to high-voltage circuits, they are highly prone to insulation breakdown and arc discharge, which can damage the connector and cause electrical safety incidents.
Therefore, for applications involving high-voltage electricity, professional high-voltage connectors must be used instead of BNC connectors. The main reasons are twofold:
Design Purpose: As a coaxial cable interface, it is primarily designed for the transmission of low-voltage signals such as radio frequency (RF) and conventional video signals, such as the 12V low-voltage signals in security systems or the analog signals in broadcasting and television, which have inherently low operating voltages.
Material characteristics: The housing is typically made of brass with plastic insulators, and no special treatment is applied for high-voltage insulation or voltage resistance. When connected to high-voltage lines, it is highly prone to insulation breakdown and arc discharge, ultimately damaging the connector and causing electrical safety incidents.
BNC connectors are not typically used in high-voltage transmission scenarios, as their inherent high-voltage resistance is limited. From a design perspective, they serve as coaxial cable interfaces, with their core functionality focused on RF and conventional video signal transmission, operating at relatively low voltages. They are suitable for low-voltage environments such as 12V security systems and analog signals in broadcasting and television. In terms of materials, they typically feature brass housings paired with plastic insulators, without special reinforcement for high-voltage applications, making them prone to accidents when connected to high-voltage lines.
