Ⅰ. Introduction to ZST 265 Epoxy Bushing
ZST 265 bushing is mainly used in the inflatable ringnetworkcabinet,can effectivelysealthecabinet insulationme dium,support and fixed cable and copper row,rated currentcan do630A 1250A, voltage level can be used for 12kV, the material of highquality epoxy resin and copper, using no local release inductionnetwork, can shield grounding or connected to live display.
Ⅱ. Features of ZST 265 Epoxy Bushing
1. Efficient Sealing and Insulation
The ZST 265 epoxy resin bushing adopts full use of the integrated epoxy resin molding process to ensure perfect compatibility with GINS. Excellent sealing performance effectively insulates leakage of insulation and provides reliable electrical insulation.
2. High Conductivity and Durability
The conductive rods use T2 copper-silver plate, which has high conductivity and low resistance thus stable current transmission. It gives high strength and corrosion resistance to ensure long-time stable operation under harsh environments.
3. Fully Shielded and Sealed Design
This bushing is applicable with the use of corresponding detachable cable connectors that will provide full shielding and sealing. In this way, electrical safety and reliability can be achieved. The design gives better performance for the whole equipment as well as reduced maintenance cost and time.
4. Quick Assembly and Simple Installation
ZST 265 epoxy bushing has been created in such a way that it would ensure quick assembly plus simple installation. This type significantly reduces the time for installation since work efficiency is improved and installation costs minimized.
