Protective Grounding Box

Protective Grounding Box

Product Description

The Protective Grounding Box serves as a critical safety component in medium and high-voltage electrical systems, providing integrated grounding and surge protection within a single, robust enclosure. This comprehensive solution incorporates zinc oxide (ZnO) surge arresters, heavy-duty grounding connectors, and monitoring elements that work in concert to safely divert lightning strikes, switching surges, and fault currents to ground, thereby preventing equipment damage and maintaining system integrity. The unit's completely sealed design and corrosion-resistant construction, available in stainless steel or engineering plastics with IP68 protection rating, ensure long-term reliability even when directly buried or installed in corrosive, humid environments. Its advanced design includes visual fault indicators and test points that enable quick status verification and maintenance without system disruption, while supporting multiple grounding configurations including single-point grounding and cross-bonding applications for utility, industrial, and renewable energy projects.

Engineered for both extreme environments and operational efficiency, the Protective Grounding Box demonstrates exceptional durability across a wide temperature range while offering flexible installation options for diverse application scenarios. The unit's modular architecture accommodates various system requirements without compromising protection capability, with the ZnO surge arresters providing rapid response to transient overvoltages through their superior nonlinear characteristics. This combination of robust construction, comprehensive protection features, and maintenance-friendly design makes it an ideal choice for ensuring continuous system operation while significantly reducing lifetime maintenance costs across power distribution networks, industrial complexes, and renewable energy facilities where reliability and safety are paramount considerations.

Feature

• 110kV Protective Grounding Boxs are used in high voltage power systems to protect the outer sheath insulation of three-phase high voltage cables from over voltage damage.

• The product internal main protector BHQ-2 cable sheath protector, the overall structure of the product is simple, sealed and reliable.

• The product shell and internal main structure are stainless steel welded, and the insulating parts are treated with moisture-proof.

• Conductor connectors are all tin-plated and crimped with bolts, which is simple to install and easy to disengage between the metal sheath of the cable and the protector during the preventive test.

• The box can be installed outdoor and is not affected by unusual weather.
