Premolded Rubber Transmission Joints
G&W’s PMJ Python® premolded rubber joints are available for 145kV and 245kV extruded dielectric cable systems. The premolded joint is part of G&W’s PythonTM family of cable accessory products. G&W has been a leading supplier of innovative underground cable accessory solutions since it was founded in 1905. With installations and sales representation worldwide, G&W continues to offer the latest technology products with world-class, time-proven performance. G&W is ISO 9001: 2008 registered for its quality systems. G&W offers a wide variety of terminations and joints for all types of cable construction through 500kV. Features:- Premolded with built-in stress control- Electrical stress control is premolded into the joint using state-of-the-art equipment. The proprietary manufacturing process uses a specially formulated silicone rubber offering superior mechanical, thermal and e
- Tested reliability- Each joint is fully tested at the factory to insure superior performance and reliability.
- Mechanical shrink technology- The one piece, silicone rubber joint is formed around a prefabricated plastic core which keeps the unit expanded as it is positioned over the cable. After the cable is prepared, the joint is easily installed by simply pullin
- Single source supplier- G&W offers a wide variety of terminations and joints for all types of cable construction through 500kV.

possibility of damage duri
- Factory premolded and expanded on core tube
- Third party tested per applicable requirements of IEEE 404, IEC 60840, and IEC 62067
The joints are supplied on an expanded core tube for maximum ease of installation. The mechanical shrink design allows easy positioning on the cable. After the cable conductors are connected, the joint is moved into place. As the core tube is removed, the joint shrinks down directly onto the cable. The mechanical "memory" of the specially formulated silicone rubber provides the proper interface pressure with the cable. There are no special installation tools or winches required. This eliminates difficult and time consuming sliding, parking and storing steps from the installation process. In addition, the pull core assembly results in a struggle-free installation, eliminating the possibility of damage or abuse to the joint body during installation. |
