Product Description
Introduction on Cable Accessories for 48/66~290/500kV
48/66kV~290/500kV high voltage cable accessories can be classified as porcelain bushing outdoor termination, composite bushing outdoor termination, full-prefabricated soft dry type outdoor termination, GIS termination, full-prefabricated silicone rubber straight through /insulating joint, assembled joint applied to any cross section, single-phase type and three-phase type for fully dry insulating branch joint, grounding box, and grounding protection box, interconnected box and sheath protector, etc.
4E-YJZGGC Plug Dry Type GIS Termination
The company produces two main 4E-YJZGGC plug dry type GIS termination, 4E-YJZGGCD short plug dry GIS termination and 4E-YJZGGCC long plug dry GIS termination, widely used for GIS electrical equipment and cable connections. They are composed of outer power, epoxy casting, prefabricated stress cone, cone prop, and tail tube. The main body of prefabricated soft silicone rubber is using imported liquid silicone rubber injection rubber molding soft dry structure, which has long-term stability of lasting hold power and electric field uniform ability. Epoxy is using epoxy resin vacuum casting molding, cone roof tight plug-dry structure. There's no need to fill insulating gas or oil, effectively ensure the long-term safe operation of the product. Our product is using multiple sealing structure which can effectively prevent the leakage of water immersion. All of the seals are using imported NBR or silicon rubber material. All of the fastener raw-material are stainless steel with good waterproof seal performance.
Our products meet the standards of IEC60859 (1999), IEC62271-209 (2007) in accordance with GIS electrical equipment. There are a little differences between the two standards, if users do not require in writing, generally based on the standard of IEC62271-209.
Main structure features:
Advanced structure: fully sealed plug dry-type structure, can firstly send epoxy casting and plugging to the GIS equipment factory and pre-installation it in the GIS equipment.
Easy installation: the length of plug-in structure of the cable is less than 300mm, dry-type with oil-free and gas free, greatly reducing the labor.
Note: according to the requirements of IEC 62271-209 and GB/T 22381-2008, the installation dimensions of GIS termination can be divided into short type and long type (The top of the sketch map is a long type).
