Substation

Turner has accumulated more than 50 years proven field experience in air break switches. That means you get an easily installed, easily operated heavy-duty switch that provides maximum mechanical and electrical performance under all operating conditions.

Its heavy-duty construction, proven reliability and ease of operation make the TCV2 switch perfect for demanding substation and line operations, such as breaker isolating and bypassing, transmission line and bus sectionalizing, isolating arrestors, metering equipment and other apparatus.

The 600 Amp switch can be easily upgraded to 1200 Amp.

Internal construction is simple, and virtually maintenance-free. The straight-forward, simple design provides smooth, easy operation, regardless of switch mounting attitude.

TCV2 switches can be easily mounted in any position: horizontal, Vertical, or Inverted, with minimal structure requirements. The low silhouette and side-opening design make it particularly applicable for low overhead clearance applications. The "V" configuration reduces base mounting requirements, lowering structure costs.

Concerns over station designs and appearances can be minimized due to the TCV2's low profile construction.

Right hand or left hand opening can be specified at time of order.

Group operation is accomplished with an interphase pipe, group operated control pipe, outboard bearing, Vertical operating pipe and swing handle operator.

Switch operation
Moving parts in the blade assembly area are restricted to only one area. The terminal pad to blade interface is threaded, silver-plated and spring-loaded to ensure excellent current transfer as well as corrosion- and contamination-resistance.

Arc transfer is easily accomplished with simple, easily maintained, stainless steel arcing horns. The horns are located away from the main current carrying contacts, eliminating any potential damage to critical, primary current-carrying surfaces.

An optional high-speed, quick-whip assembly enhances the ability of the product to drop line or bus charging currents, as well as transformer magnetizing current.

The extra heavy mounting base combined with the use of massive current carrying components helps ensure that contacts maintain proper alignment.

The rotating bearing assembly consists of two tapered roller bearings, which are adjusted and lubricated at the factory and require no further attention for the life of the switch.

Reverse Loop Contacts
Massive contact construction provides positive mating, even if some blade misalignment occurs, during seismic activity or under heavy fault current. Silver-to-silver contact surfaces provide low resistivity with high conductivity.

Hinge Terminal Pad
The pivot point for the pad is directly over the insulator. This provides less bending moment, providing a strong load bearing pad. The terminal pad threads are silver plated, and, once screwed into the hinge casting, sealed by means of a Buna "O" ring seal.

Current Carrying Parts
The TCV2 Aluminum switch has both Aluminum and silver plated copper alloy live parts. Exposed current transfer points are silver to silver.

Insulators
NEMA standard strength gray porcelain insulators of the same voltage rating as the switch will be supplied, unless specified otherwise.

Switch Adjustment
Four leveling screws are provided on the sub-base of each insulator stack, to facilitate easy alignment after assembling the insulators on the switch. Adjusting the screws raises or lowers the end of the switch blade.

Base
Standard bases are hot-dipped, galvanized, rigid, steel sections. Lifetime bearings, requiring no lubrication, and open-close stops are built into the compact assembly.

Make Your Center Break a Load-Break Switch
For more than 35 years, Turner Electric's TECO-Rupter^® Vacuum Interrupters have been the technology of choice for loop and load-break applications because of their current-interrupting ability, superior reliability and ease of application.

The TECO-Rupter offers industry leading performance levels including superior TRV ratings compared to other load-break technologies such as SF6, longer service life and greater interrupting capacity. No other load-break device provides 5,000 full load operations at either 2,000 or 3,000 Ampere ratings and a TRV rating up to 57kV.
