Summary of product being
SF6 Gas Insulated metal-enclosed Switchgear (Gas Insulated Switchgear, hereinafter referred to as the GIS) consists of circuit breaker, disconnecting switch, grounding switch, transformer, lightning arrester, busbar, casing or cable terminal electrical components such as direct connection to each other, all components in the earthing metal casing, casing is used for insulation and arc extinguishing SF6 Gas.
ELH1 type GIS series products of our company (hereafter called sacsc) and Russia all Russian electrician institute (GUPVEI), academy of China power switch is the crystallization of the tripartite cooperation, in the process of r&d, manufacture, inspection and absorption and application of the international most advanced technology and operating experience, with advanced technology, mature and reliable, easy to maintain, etc.Main technology in the domestic leading level.
ELH1 type GIS rated voltage is 126 kv, short circuit current of 40 ka.Equipment meets GB7674 the 72.5 kV and above gas insulated metal-enclosed switchgear, such as standard rules.Suitable for indoor and outdoor installation and operation.
Feature a product structure being fostered design
Take up the space is little
High reliability.
Sealing part.
Light weight.
Life is long.
Building block of the module design.
Widely used in plant with large unit testing, installation period is short.
Three-phase box structure.
Standard modular design module.These separate box modules or components can be combined at random, greatly simplifying the equipment design and installation planning, very easy to realize the bridge connection, single bus section, double bus section, circuit breaker, polygon, etc. Various kinds of connection mode.
Equipment shell choose the corrosion protection of aluminum alloy manufacture, its weight is very light, has greatly reduced the foundation construction investment, no hysteresis losses at the same time.
According to the needs of different users, there are horizontal and vertical two structure scheme for choice.
