Product Features

GTZ-15-300 YT/GZ-4 series three-phase spark-free connectors are suitable for use in oil exploration, drilling platforms, circuit, and MCC room power distribution connections, characterized by reliable contacts and excellent sealing performance. They are also rainproof, shockproof, and dustproof.

The connector consists of a plug and a socket, with the plug being movable (YT), and three options available for the socket:

1. Panel fixed (GZ),

2. Movable (YZ),

3. Inclined fixed socket (XGZ).

The connection between the plug and the socket is a bayonet-type quick connection, with the contact terminals being crimped to the wire ends. The contact terminals are supported and positioned by elastic tooth rings, and the plug is designed with a detachable structure for ease of disassembly and assembly. The contact terminals of the plug are silver-plated, and the shell is made of die-cast aluminum alloy.

Model labeling method:

YT – Mobile plug, GZ – Fixed socket, Y2- Mobile socket.
Number before letters: working current; Number after letter: number of needles and holes.

J: Sowing needle; K: Jack; The number of needles and holes marked at the end of the letter is three-phase four pole.

Example: 60YT/GZ represents a 60A three-phase four pole broadcasting head and socket.

100YT-5J/GZ.5K represents a 100A three-phase five pole plug and socket.

Mark during inversion: 100YT-5K/GZ.5J.
