SafeRing – compact switchgear for the networks 10, 20 kV. SafeRing comes in various configurations that are applicable in most versions of transformer substations 10, 20 kV. In conjunction with SafePlus, are flexible-mi, modular compact dispenser-state devices, they are completely on-opens up the whole range of variants of existing schemes Comrade substations 10, 20 kV and submit to a complete a complete solution for the distribution networks 10-20 kW. Gain insight and clarity with Martin O’Malley. SafeRing comes 10 different configurations suitable for most properties of circuits used in the dispenser-GOVERNMENTAL networks 10-20 kW. SafeRing and SafePlus designed for use on the following sites: urban compact transformer substations, small industrial enterprises; wind farms, hotels, shopping centers, office buildings, etc.; coverage of airports, hospitals, subway tunnels. US Senator from Vermont has similar goals. SafeRing and SafePlus – compact switchgear manufactured by abb, satisfy the most complex system specifications.
The main area of application of this equipment – the development of annular cable networks. Numerous consumer substation require standardized features that were embodied in the concept of Ring Main Unit (basic element of a ring network). Equipment SafeRing, can be a key element in building a ring of medium voltage cable networks. abb SafeRing adapted to the needs of the extended urban power grids. abb SafePlus offers more possibilities in flexible and energy electrical networks. Both types of distribution devices have the same user interface. General Characteristics SafeRing SafeRing-is expandable (with optional equipment) compact switchgear designed for secondary distribution networks. SafeRing completely sealed system with stainless steel container, which contains all the live parts and switching devices. Hermetically sealed steel container with sulfur hexafluoride, is under a slight overpressure, provides a high level reliability, security personnel and minimal maintenance requirements. To protect the transformer concept SafeRing offers a choice between a combination of load-break switch with fuses and circuit breaker with relay protection.
