Line tension disconnect Ruggedly built and reliable, the type SE and type SEL line tension disconnects splice right on to the line. Offering quick and safe line maintenance, they safely support the conductor while providing the required insulation gap. Type SE and type SEL line tension disconnects offer the following advantages: • • Porcelain insulators optional Multiple insulator units per switch for improved safety L ightweight design minimizes conductor loading – may be used with smaller conductors Slim 4 1/4” diameter insulator profile – easier to cover for hot line work Rigid square...

Strain insulator assembly During and after assembly, rigorous quality control and tensile proof tests ensure that this is a strain insulator worthy of a type SE or type SEL line tension switch. High-strength alumina porcelain Tensile forces Compressive forces A line tension switch, by the nature of its application, must mechanically support the line and provide highvoltage electrical insulation when the switch is in the open position. Almost since the inception of the electrical power industry, the most dependable means of providing these two basic functions has been the porcelain strain...

Type SE with quick break All the quality of a standard switch, but with a quick-break device T he quick-break option is available on all distribution class hookstick disconnects Add “QB” as a suffix to the catalog number (for example: 127QB) 180° blade catch is standard on all 200 kV BIL quick-break switches A ll other dimensions and ratings are the same as the standard switch equi

Type SEL with Saf-T-Gap interrupter The type SEL offers all the benefits of the standard type SE switches plus the same high quality Saf-T-Gap expulsion interrupter. The plug-in Saf-T-Gap interrupter changes in seconds with a standard shotgun-style hookstick. • 180° blade catch is standard on catalog number 340 Available as an option on catalog numbe

Line tension disconnect with closer arm Pull the switch to open via the pull ring. Pull the switch to close via the closer arm. The closer arm option allows for installation of the switch farther away from the crossarm and is applicable to most type SE and type SEL switches. Not compatible with switches having a 180° blade catch Add the letter “V” as a suffix to the catalog number (for example: 127 V) Retrofit kit available to retrofit existing type SE and type SEL swit

The type LER line tap disconnect is a rugged and reliable disconnect device that may be used either in tension or clamped onto the line for a wide array of cable-riser and crossover applications. These switches feature a sturdy and well-ventilated square tubular copper blade and high-pressure silver contacts for superior current carrying characteristics. In addition to a positive latch, all switches come with an exclusive opening mechanism to ease hookstick operation even after years in service. Many available options, accessories and mounting configurations make the type LER a flexible...
