35kV Cable Distribution Cabinet

• Enclosure: Typically made of stainless steel, featuring waterproof, dustproof, and corrosion-resistant properties. Available in outdoor floor-mounted or indoor types to suit different installation environments.

• Key Parts: Centered around cable connectors (e.g., plug-in, pre-molded types), complemented by insulation supports, grounding devices, and inspection windows (in some models). It has no complex operating mechanisms, resulting in a relatively simple structure.

• Insulation Method: Mainly air insulation or solid insulation. Some eco-friendly models use dry gas insulation to avoid the environmental risks associated with traditional SF₆ gas.

1.  Key Features

• Maintenance-Free: No moving mechanical parts; pre-molded connectors ensure high reliability after installation without frequent inspections.

• Flexibility & Convenience: Compact size allows direct floor-mounted installation without the need for a distribution room, enabling quick integration into cable networks for temporary or permanent branching needs.

• Safety Insulation: Reliable insulation protection for connectors and conductive parts, combined with proper grounding, effectively prevents electric shock and short-circuit risks. 4. Primary Applications Suited for 35kV high-voltage distribution systems, its main applications include:

• Urban grid upgrades, branching main road cables to supply surrounding areas;

• Connecting high-voltage cable lines between workshops or zones in industrial parks and large mining/industrial plants; 

• Renewable energy sectors (e.g., wind or solar farms), aggregating or distributing high-voltage cable power within the facility.

4.Key Terms Explained: 

• Cable Distribution Cabinet: A passive enclosure for branching/joining cables without switches. 

•Pre-molded Connector: A factory-assembled, sealed cable joint for quick installation. 

• Solid Insulation: Non-gaseous insulation (e.g., epoxy resin) enhancing safety and compactness.
