Product description
- Product Description
-
Butterfly porcelain insulators are commonly used insulating devices in overhead power transmission lines, serving both electrical isolation and mechanical fixation functions. Their features and applications are as follows:
Structure and Materials
Butterfly porcelain insulators are made of ceramics (main components include high-purity alumina and zirconia), featuring high temperature resistance and corrosion resistance. The typical structure includes an iron cap, ceramic parts, and steel foot, assembled with cement adhesive, suitable for insulation of high-voltage transmission lines and external insulation of power station equipment.
Core Functions
Electrical Isolation: Achieves insulation between conductors and grounded components to prevent voltage breakdown causing short circuits.
Mechanical Fixation: Fixes conductors to poles or crossarms through metal connectors, bearing long-term tensile, bending, and other stresses during operation.
Application Scenarios
Low-voltage Distribution Lines: Widely used in rural distribution networks, fixing conductors horizontally or vertically, supporting bolt or crossarm installation.
Tension Poles/Angle Poles: Commonly used on terminal poles, tension poles, and angle poles, used in conjunction with suspension insulators.
Usage Limitations
Ambient Temperature Range: -40℃ to +40℃
Altitude not exceeding 100 meters
