Types of high Voltage Connectors and Their Precautions

There are various high voltage connectors which can be used for the transmission of electrical power. It has mainly scientific and medical applications used for easy connection. This helps the wires to transfer quickly the power from a power source to the device.

High voltage connectors are mainly classified into –

Non-shielded high-voltage cable connectors
They are high voltage connectors used without any shield for single core high voltage cables and high-voltage Teflon cables. There is no standard in the cable connectors, makers use as per their requirements in the cables.

Coaxial high-voltage cable connectors

These are shielded single core coaxial cables such as BNC, MHV or SHV. Some other high voltage connectors are also available like SMA, SMB and SMC but they cannot be used for high voltage applications. Some other coaxial connectors are also available and is mainly used as proprietary applications.

Multicore high-voltage cable connectors

These are mainly used in medical field especially for X-ray tubes, electron beams, ion beams, etc.

Common types of high-voltage connectors include

Miniature High Voltage (MHV)
It is used to connect high voltage coaxial cables to varied devices. When you are transmitting a high power then you cannot transmit different characteristics cables and connectors. It has to be of same frequency. Though, MHV and BNC have the same usage, still MHV is commonly used and they both cannot be connected to each other owing to different properties.
Safe High Voltage (SHV)

These connectors can be used at high voltages than MHV. Because of its insulation concentration on the center it increases the creepage distance and allows better electric flow. They cannot be connected to HV or BNC connectors.

Precautions for use

• The voltage stated is of standard value. Before using a connector, do cross-check their voltage capacity with the manufacturer.
• Danger associated with commercial lines to high voltage connectors are incomparable. Hence, very important to check the electrodes and the voltage capacity.
• The plugs have to be connected properly else pins may get damaged causing disconnection or short-circuit.
• Wiring mistakes has to be avoided in case of multiple connectors. This can result in total disruption of the equipment.
• Cleaning of the connectors should be done periodically in order to avoid creepage discharge. Greasing should also be done for the connectors.
• Avoid keeping metal debris on the cables or connectors which can cause holes resulting in short circuits.
• Avoid any close vicinity to flammable objects as it is high voltage and transmits high energy.
