35kV， Suitable for three-phase AC 50Hz high-voltage overhead lines.
Composite cross arm: using fiberglass core rod and silicone rubber umbrella skirt, weight reduced by 60%, strong impact resistance, hydrophobicity: the surface energy of silicone rubber is low, and it still maintains high insulation under polluted conditions (pollution flashover voltage increased by 2 times).
| Product model | Rated voltage（KV） | Rated bending load（KN） | Structure hight (mm) | Minimum arc distance(mm) | Minimum creepage distance (mm) | Lightning impulse voltage (peak) (KV) | 1 min power frequency wet voltage (KV) |
| FZSW-35/8 | 35 | 8 | 510 | 455 | 1320 | 230 | 95 |
Traditional overhead power lines: ceramic crossarms (SC-185/210 series) are preferred for rural power grid renovation, reducing overall costs by 20%;
Urban network renovation: Composite crossarm (FS-35-5 type) is suitable for narrow corridors, reducing tower height by 40%;
New energy station: FPQ-35-6 composite cross arm is used for wind/photovoltaic booster stations,
35kV cross arm insulators promote line upgrades through material innovation. Ceramic models focus on economy, while composite models emphasize environmental adaptability. Selection requires comprehensive consideration of pollution level, mechanical load, and full life cycle cost
