As a specialized manufacturer of high-voltage electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. leverages its expertise and modern production facilities to deliver reliable and efficient solutions for the power distribution industry. Our 35KV T-type Plug-in Branch Box is engineered specifically for the demanding environments of wind farms and substation ring main lines. This product represents our commitment to providing components that enhance grid stability, simplify maintenance, and ensure safe power distribution, making it an ideal choice for utility companies and project developers seeking robust and adaptable connection systems.
This branch box is designed to facilitate secure and flexible branching connections within 35KV ring main unit (RMU) networks. Its core value lies in its ability to provide a reliable, insulated, and easily serviceable junction point without the need for complex on-site assembly or specialized tools. The plug-in design significantly reduces installation time and operational downtime, which is critical for maintaining continuous power flow in wind farms and substations.
Key Features and Technical Advantages:
- Modular Plug-in Design: Enables quick connection and disconnection of feeder lines to the main ring. This modularity allows for future network expansion or reconfiguration with minimal disruption.
- Superior Insulation and Sealing: Constructed with high-performance insulating materials and featuring a standard IP68 sealing rating, the box effectively withstands harsh outdoor conditions, including moisture, dust, UV radiation, and wide temperature fluctuations.
- Enhanced Safety: The fully insulated live parts and secure locking mechanism prevent accidental contact and ensure operational safety for personnel. The design often includes visible break indicators or earthing switches (available upon request).
- Durable Construction: The housing is typically made from corrosion-resistant materials like coated aluminum alloy or stainless steel, ensuring long-term performance even in coastal or industrial atmospheres.
- Flexible Configuration: Available in various port configurations (e.g., 1-in, 2-out) and compatible with different cable types and terminations (e.g., heat-shrink, cold-shrink). Custom configurations to match specific project layouts are available.
- Low Maintenance: The sealed, maintenance-free design reduces lifecycle costs. Internal components are designed for high electrical endurance and resistance to partial discharge.

Frequently Asked Questions (FAQ):
-
Q: What is the primary advantage of a "plug-in" design for a branch box?
A: The primary advantage is operational efficiency. It allows for rapid, tool-free connection and disconnection of cables, drastically reducing installation and maintenance time compared to traditional welded or bolted joints. This minimizes system downtime. -
Q: Is this branch box suitable for direct burial installation?
A: While the standard unit is designed for pole or ground mounting with appropriate brackets, versions with enhanced mechanical protection for direct burial can be discussed as a custom option. The IP68 rating ensures suitability for wet and buried conditions. -
Q: Can it be integrated with monitoring or smart grid systems?
A> Yes, options are available. The box can be configured with accessories such as fault indicators, temperature sensors, or remote communication modules to enable condition monitoring and integration into smart grid networks. -
Q: What cable types and sizes is it compatible with?
A: It is typically compatible with standard 35KV power cables (e.g., XLPE insulated). Specific compatibility depends on the chosen termination adapter (heat-shrink, cold-shrink, pre-molded). Please provide your cable specifications for accurate configuration. -
Q: How does it perform in extreme cold environments like those found in some wind farms?
A: The product is tested and rated for operation from -40°C. The materials used (elastomers, seals) are selected to maintain flexibility and sealing integrity at low temperatures, ensuring reliable performance. -
Q: What is the expected service life under normal operating conditions?
A> With proper installation and within specified operating parameters, the branch box is designed for a service life exceeding 30 years. The maintenance-free design of key internal components contributes to this longevity. -
Q: Are spare parts and accessories readily available?
A: As the manufacturer, we maintain an inventory of critical spare parts (like plug-in modules, seals) and standard accessories to support your maintenance needs and ensure long-term supply continuity. -
Q: What is the lead time for a standard order?
A: Lead times vary based on order quantity and specific configuration. For standard models, typical production lead time is 4-6 weeks. We recommend contacting our sales team for a precise quotation and delivery schedule.
