Product Advantages
1. The porcelain bottle model is made of high-strength electroceramic, with stable insulation performance; the silicone model is resistant to dirt, weathering, and impact, reducing the risks of outdoor aging and damage, and is suitable for complex environments such as rain, snow, sand, and coastal salt spray.
2. Integrated metal frame + brass conductive components, with low contact resistance and low heat generation; the switch disconnection position is clearly defined, forming a visible break, meeting the safety standards for power maintenance procedures of "power off - electrical testing - grounding".
3. The base is equipped with universal installation holes, allowing it to be directly fixed onto poles or supports without any additional modifications. Both single-pole and three-pole options are available, suitable for new lines as well as the upgrading of old lines.

FAQ
1. How to choose between the porcelain bottle version and the silicone version?
For ordinary dry environments, choose the porcelain bottle model, which offers good value for money; for coastal, high-humidity, and heavily polluted environments, select the silicone model, which has stronger weather resistance and a longer lifespan.
2. Is the product suitable for overseas markets?
The Porcelain Disconnector Switch complies with international standard power requirements and is suitable for 11kV/33kV power distribution systems in regions such as Southeast Asia, the Middle East, and Africa. It also supports the provision of export certification materials.
3. What should be noted during the installation process?
During installation, ensure that the circuit breaker operates smoothly and the grounding is reliable. For outdoor installations, it is recommended to pair with a rainproof cover to extend the service life.
