Type PMG80, 245 kV, up to 80 kA Power Circuit Breaker | 3
ABB has a long history of supporting utilities’ needs for expanded dead tank breaker performance in response to the growing demands of a continuously evolving power grid. ABB offered the first 80 kA rated modern SF
6 dead tank breakers in 1998,
helping to sustain existing substations during the midst of a significant increase in power demands.
Dead Tank Circuit Breaker Type 245PMG80
Why 80 kA? Line burdens will continue to increase as more generation is added to the grid. A major driver is the growing number of states that are enacting mandatory Renewable energy Portfolio Standards (RPS). To help fulfill RPS commitments, utilities are purchasing increasingly greater proportions of their marketable electricity from independent power producers (IPP), much of which is derived through wind turbines. The proliferation of IPP’s is seen as a certainty as wind farms become more competitive with generation modes based on traditional resources, and as encouraged by environmental regulations and/or governmental support.
Incremental generation by IPP’s may not only stress existing transmission lines beyond their safe power delivery capacity, it may also unfavorably alter the electrical characteristics of one’s system, rendering existing breakers unable to safely perform routine switching and interrupting duties. Breakers having enhanced interrupting ratings offer a ready solution to systems with rapidly increasing short circuit demands. Added generation may also unfavorably increase system reactance, resulting in X/R ratios well in excess of the ANSI standard value of 17. As a result, existing breakers may fail to properly interrupt certain faults, even if their rated capability is not exceeded. That challenge may be best solved by appropriately “over-sizing” the breaker’s interrupting capability. For example, depending on the disparity of system X/R from standard, an 80 kA breaker may be required to properly interrupt faults on a 63 kA system.
With ABB’s 245PMG80 breaker, utilities have a formidable solution to address line switching and protection demands necessitated by replacement of obsolete equipment, or by a power grid over-stressed as a result of added generation and/or excessive X/R ratios.

Single-piece interrupterOur single-piece modular interrupters utilize state-of-the-art technology that minimizes line-to-ground insulation components and allows for simplified removal and replacement.
Type PM circuit breaker familyWith over 30,000 breakers delivered to date spanning voltages up to 800 kV, the ABB type PM dead tank circuit breakers remain the most purchased brand in the industry. This is due to their low cost of ownership and strong performance, backed by industry-leading service and support.
Insulating mediumThe type PM uses SF
6 as the insulating medium.
Through innovative design, manufacturing techniques and monitoring technologies, ABB has invested in reducing SF
6 leaks. The PM line utilizes less SF
6 than
competitive designs.
ShippingThe type 245PMG80 is shipped to site for domestic deliveries on a double-drop air ride trailer. It comes assembled, less mechanisms, with positive SF
6 pressure. The breaker is
disassembled and packaged for applications which require higher insulation ratings or for non-domestic shipments.

BushingsABB offers a host of bushing options for our customers including a full line of silicone based polymer insulators through 800 kV. ABB utilizes tapered designs, where feasible, to reduce the SF
6 volume in our customer’s fleet.
TanksSingle-piece tanks are ultrasonically cleaned, then leak tested in a vacuum sealed chamber using highly accurate helium mass spectrometer leak detection. Tanks are ASME pressure vessel tested and given a number stamp for certification.
Control cubicleABB prides itself on offering generously-sized control cubicles at workable heights to vastly improve access to the equipment over its lifetime.
Bushing current transformersABB utilizes slipover BCT designs for our dead tank product line which allow for cost effective and efficient removal or exchange without removing the bushings.

HMB 8.11 mechanismThe type HMB-8 class spring-hydraulic mechanism, externally mounted beneath the pole linkage system, provides the driving force to gang-operate the breaker’s high performance puffer interrupters. Mechanical energy, stored in a stack of compression disk springs, is hydraulically translated to the operating shaft. Spring charge is automatically maintained by the operation of a universal motor and hydraulic pump. The fully integrated mechanism is self lubricating, hermetically sealed to the atmosphere and weather protected, affording excellent reliability and long term stability and is backed by an industry-best 10 year warranty.
Mechanism data
Typical installations
The compact design of the 245PMG80 is ideal for new or existing substation layouts for voltages up to 245 kV. The breaker fits within many existing footprints and can be used to quickly address the need for greater protection for minimal cost.
Those familiar with the PM line of breakers can typically install and commission the breaker within 1-2 days, given a prepared foundation. Mechanisms are installed at site using simple couplings and pre-wired industrial plug connections.
