Frequently Asked Questions
What is the difference between transmission cable accessories and distribution cable accessories?
The biggest visual difference between transmission cable accessories and distribution cable accessories is the size. Looking further into why the sizes are significantly different has to do with the electrical fields and the cables they interact with. The higher the voltage the more stress relief is needed during the terminating and jointing processes.
How do I pick the right accessory for my cable?
- The first step to picking the right accessory for your cable is to identify the voltage class, insulation type, and conductor material of the cable.
- For voltages 15kV-46kV, the G&W Electric distribution cable accessories offerings will be where to start.
- If there are some dimensional unknowns and the cable is single conductor, the Slip-On line will be best.
- The Capnut, Sodertite, and Crimptite terminations are field assembled terminations that are great for three conductor applications.
- For voltages 69kV-500kV there are two types of cables that can be used. Solid dielectric and paper insulated.
- For solid dielectric the G&W Electric Python lines provide a wide variety of terminations and joints.
- For paper insulated cables the G&W Electric ATA/ATL lines will be where you find your cable accessories.
What is a cable accessory?
- A cable accessory is typically referring to terminations/potheads that are used to connect underground cable to either an overhead bus, cable, or piece of equipment.
- Joints/splices that connect two pieces of underground cable.
