Post Composite Insulator

<h2>Stable post insulation for equipment and bus support</h2><p>Post composite insulators support energized parts while maintaining the required electrical clearance. Their lightweight composite construction is suited to outdoor equipment, substation assemblies and distribution applications.</p><h3>Typical applications</h3><ul class="grl-pro-copy__list list-paddingleft-2"><li><p>Substation bus and conductor support</p></li><li><p>Outdoor switching assemblies</p></li><li><p>High-voltage equipment insulation</p></li></ul><h3>Selection guidance</h3><p>Confirm rated voltage, bending load, mounting dimensions, creepage distance, pollution level and operating environment.</p><p>Final ratings, dimensions and accessories should be confirmed against the project specification and applicable standards before ordering.</p><h3>Technical Parameters</h3><table><thead><tr class="firstRow"><th>Model</th><th>Structure</th><th>Rated Voltage (kA)</th><th>Rated Mechanical Load(kN)</th><th>Creepage (mm)</th><th>Lightning Impulse Withstand Voltage (kV)</th><th>Power Frequency Withstand Voltage</th><th>Material</th></tr></thead><tbody><tr><td>DNFZSW-11/10</td><td>Unequal</td><td>11</td><td>4</td><td>300</td><td>75</td><td>42</td><td>Silicon Rubber</td></tr><tr><td>DNFZSW-36/10</td><td>Unequal</td><td>36</td><td>6</td><td>720</td><td>170</td><td>80</td><td>Silicon Rubber</td></tr><tr><td>DNFZSW-66/12.5</td><td>Unequal</td><td>66</td><td>8</td><td>2100</td><td>410</td><td>185</td><td>Silicon Rubber</td></tr></tbody></table>
