Standard: EN - Signifies compliance with European Norms. The key standard defining this type is EN 50180 ("Bushings up to 36 kV and from 250 A to 3,15 kA for liquid filled transformers"). General requirements likely also meet EN IEC 60137.
Voltage Rating: 36kV - Represents the maximum system voltage (Um). This corresponds to a nominal system voltage (Un) of 33 kV.
Current Rating: 250A - The rated continuous current (Ir) the bushing conductor is designed to carry.
Type: Type 4 - This designates a specific interface type according to EN 50180.
General Description
Application
Used primarily for outdoor installation on distribution transformers within 36 kV electrical systems in regions following EN standards. It's specifically chosen when the transformer design requires the larger Type 4 mounting interface.
Material
Commonly made from high-quality electrical porcelain (usually brown or grey glazed) or composite materials (like silicone rubber sheds over a fiberglass core).
Function
It reliably insulates the live conductor from the grounded tank, provides a sealed passage for the conductor, offers mechanical support, and serves as the external connection point. The Type 3 classification ensures it fits transformer tanks prepared with the corresponding larger mounting arrangement.
Creepage Distance
This parameter (e.g., 525 mm, 600 mm, 720 mm, 935mm etc.) must be selected based on the expected environmental pollution level where the bushing will be installed, following guidelines in EN/IEC standards.
