15 kV Cable Couplers

Benefits: One of the most effective methods to prevent decoupling of energized couplers

Mechanical interlocking is one of the most reliable means for promoting and ensuring safety   around high voltage electrical equipment. By design, 15 kV class couplers are not intended to be disconnected when energized. There are safety features incorporated into these products to prevent disconnecting couplers under load, as well as features to limit the danger in this event. However, utilizing a mechanical interlocking   arrangement in combination with the 15 kV design features, and safety procedures, provides further protection for personnel and equipment.

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.

Benefits: Skid mounted junctions can prolong cable and coupler life and enables plug / plug cable arrangement

Incorporating a plug to plug cable arrangement is the major advantage that can be gained with a junction box. For larger cables in particular, it can take considerable time and energy to add or remove a length of cable from a mining production environment. With a plug to plug arrangement, the cable can be laid out in either direction as the connector is the same on both ends. Traditional jumper cable arrangements are plug to receptacle, like common household extension cords, and so it is possible to lay out a cable “incorrectly” with this arrangement.

Benefits: Provides power and monitoring to multiple pieces of mobile equipment with less cable

Splitter boxes are the ideal solution   for reducing cable requirements in production areas.  Splitter boxes enable 2 or more pieces of equipment to draw power from 1 cable feed. Splitter boxes have  a wide range of options including indicator lights and ground wire monitoring. If equipped with optional live  end covers, it is possible to energize the splitter  box with one or more unused outlets.

Benefits: Skid mounted coupler can prolong cable and coupler life

The use of skids with couplers can help   to dramatically extend the life of cable and couplers by keeping them off the ground, and increasing their visibility to personnel and mobile equipment. For personnel, increased visibility means a safer work environment;   and for equipment, it means less downtime.

Patton & Cooke couplers are designed to ensure a long working life if they are left on the ground, however skid mounting couplers will provide added protection for the cable and couplers. And as the real cost of coupler ownership includes installation,   maintenance, and materials, extending the life of couplers will help to reduce these costs as well.

Extending the life of couplers means less maintenance and more machine uptime!

Benefits: Enables splitter boxes to be safely energized with 1 or more circuits disconnected

Live end covers were designed for use with splitter boxes equipped with ground wire monitor protection devices. Live end covers provide incorporate protective covers, insulated phase tubes, and end of line devices which enable safe energization of a splitter box even if one or more circuits have been disconnected.

Benefits: Simplify the installation   process for equipment mounted couplers by ordering mounting hardware with your coupler

C80 Series Panel mount couplers are not supplied with hardware for mounting to equipment or enclosures. The size of the hardware will depend on the thickness of the enclosure wall. To mount your coupler you can obtain hardware equivalent to the sizes indicated below. Patton & Cooke can supply these as well as an optional accessory with the part number

For an enclosure with 1/8″ – 1/4″ wall thickness the following mounting hardware kit is recommended:

(8) GB-0814 : 1/2″ x 1-3/4″ Galvanized bolts

(16) GFW-08 : 1/2″ Galvanized flatwasher

(8) GLW-08 : 1/2″ Galvanized lockwasher

(8) GN-08 : 1/2″ Galvanized nut

Kit Part Number: C80F3xxx

Benefits: Reduces strain on enclosure and cable

Patton & Cooke recommend using 3/8″ hardware for gear mount couplers and 1/2″ hardware for flange mount couplers to help ensure a robust installation and to help maintain IP protection in mining, industrial, and marine environments. However incorporating elbow adapters with gear and flange mount couplers can reduce strain on the enclosure and the cable, helping to maximize the performance and service life of your equipment.
