Powell distribution switch solutions are available in subsurface, padmount, and transformer mounted constructions for use in load break, source transfer, and fault interrupting applications. We offer a wide range of standard designs but have the capability to custom engineer a solution for your specific need.
In service and meeting the needs of utilities and industrial users worldwide, we offer a robust and cost-effective answer to electrical distribution requirements. Contact our sales team to see how Powell switches can work for you.
Powell offers a wide selection of padmount SF6 switches for systems rated 15kV through 38kV, 600A continuous current. Powell’s padmounted switches may be provided in up to 6 switched ways. Padmount mounted switches typically are provided with either front or rear termination access. Powell will configure to meet the customers’ requirements. Switches can be operated either manually or through distribution automation to meet your requirements. No matter the application load switching, line sectionalizing, fault interruption, source transfer, or distribution automation, Powell can provide a quality solution for your application.
Powell subsurface/vault style medium voltage switches are available for systems rated 15kV through 38kV, 900A continuous current. Subsurface vault switches utilize a medium voltage switch assembly mounted below ground level in a vault or chamber. These are typically used for underground distribution systems and a straight-forward and simple method of system distribution. A wide variety of switch configurations are possible so as to provide a truly custom-engineered solution for your application.
Powell has been providing solutions to automation and voltage loss restoration for more than 30 years. Whether the requirement is for a standalone automatic transfer switch, an automatic transfer switch with load fault protection, or a multiple source system reconfiguration with high speed transfer, Powell’s experience in providing preferred/alternate, main-tie-main, and multisource load shedding allows us to provide a solution that meets or exceeds our customer's requirements.
Vacuum Fault Interrupter
Powell’s fault interrupters are magnetically actuated to provide a fault interrupter that does not need an added mechanism to provide automated operation. Since the base interrupter has no manual operating handle, potential SF6 leak points are eliminated. If a manual trip is required, then a manual trip handle can be provided. Fault interrupter ratings 15kV through 38kV, 600A, Fault interrupt/Fault Close 12kA, or 25kA.
