It looks like you’re referring to a specific type of electrical connector or termination used in high voltage applications, particularly for 11kV systems. Here’s a breakdown of the components in your query:

1. 11kV: This indicates the voltage rating of the connector, which is suitable for systems operating at 11,000 volts (11 kV).
2. Male-Female: This suggests that the connector has both male and female parts. The male connector typically has protruding pins, while the female connector has corresponding holes to accept the pins.
3. A-B Part: This likely denotes a specific type of connector design or configuration. In many high voltage applications, connectors may be categorized into various parts (A and B) based on their function or configuration.
4. 400A: This specifies the current rating of the connector, indicating it can handle up to 400 amperes.
5. Brass: This refers to the material used to make the connector, which is commonly used for its good conductivity and resistance to corrosion.
