In designing a trailing cable coupler for 25 kV operation, Patton & Cooke determined that the coupler had to operate efficiently at this high voltage while still being maneuverable in the field.
First a new idea, then a new product evolved; the 25 kV Cable Coupler & Coupling System. The system incorporates trailing cable couplers, support skids with hoisting mechanism, accessories, and tools. All the equipment necessary for a complete and manageable 25 kV, 650 Amp cable connection.

EPOXY POWDER COATING
Benefits: corrosion resistance, visual identification
Epoxy Powder coating provides a strong and corrosion resistant finish to aluminum coupler bodies and castings. While Patton & Cooke use alloys with the highest possible corrosion resistance, for corrosive environments such as heap leaching, marine, or underground mines with acidic conditions, Patton & Cooke recommend an epoxy powder coated finish to maximize the life of the project. Powder coating is also an effective visual indicator of coupler gender. To help reduce cable laying errors, a basic color coding scheme can help mine personnel easily and identify male and female couplers. Standard colors are shown below, custom colors are available upon request.
