33kV Silicon Combination Unit is a medium-voltage protection assembly that integrates a silicone rubber lightning (surge) arrester and a drop-out fuse cutout into one compact unit.
Key Functions:
• Overvoltage Protection: The silicon/polymer arrester protects transformers and lines from lightning and switching surges.
• Overcurrent Protection: The fuse disconnects the circuit during faults or overload conditions.
• Insulated Housing: Silicone rubber provides excellent weather resistance and high insulation strength.
Applications:
• 33kV overhead distribution lines
• Transformer protection on utility poles
• Substation outgoing feeders
Durable, weather-resistant, and essential for reliable 33kV network protection.
