As a professional manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our 35KV T-type Plug-in Branch Box, engineered for reliability and safety in modern ring main distribution systems. This branch box, featuring a shielded front connector, represents a key component for creating flexible and secure tapping points in 35KV networks. Designed with over a decade of manufacturing expertise and backed by a robust quality management system, our product is built to meet the demanding requirements of utilities and industrial power distribution projects worldwide. We understand that network uptime and personnel safety are paramount, which is why this branch box incorporates advanced shielding and plug-in technology for safe, live-line operation and minimal maintenance.
The core design of this T-type branch box centers on providing a fully shielded, compact, and pluggable solution for branching from a ring main unit (RMU) or switchgear. The shielded front connector is a critical feature, ensuring that the high-voltage connection point is completely enclosed in a grounded metallic shield. This design effectively contains the electric field, prevents partial discharges, and significantly enhances operational safety for personnel working nearby. The plug-in design allows for the easy connection and disconnection of the cable feeder, facilitating quick installation, testing, and future network reconfiguration without extensive downtime.
Key Technical Features and Advantages:
- Full Shielding Technology: The front connector assembly is fully encapsulated by a metallic shield connected to earth. This design offers superior protection against electric shock and minimizes electromagnetic interference.
- Safe Plug-in Interface: Utilizes a robust, self-aligning plug-and-socket system. The design often includes safety interlocks to ensure the unit is earthed before the plug can be removed, adhering to strict safety protocols.
- Compact and Modular Construction: Its T-type form factor is optimized for space-saving installation in cable trenches, substations, or compact RMU extensions. The modularity allows for easy integration into existing systems.
- High Dielectric Strength: The insulation system, whether using SF6 gas or advanced solid epoxy, is designed to withstand lightning impulses and switching overvoltages common in 35KV systems.
- Corrosion-Resistant Enclosure: The outer enclosure is typically made from galvanized steel or stainless steel, coated with anti-corrosion paint, ensuring long-term durability in harsh outdoor environments (IP65/IP67).
- Visual Indication and Earthing: Equipped with clear visible break indicators and a reliable earthing switch to provide a safe working zone for maintenance crews.

Frequently Asked Questions (FAQ)
-
What is the primary function of this T-type branch box?
This box serves as a fully shielded tapping point in a 35KV ring main system. It allows a feeder cable to be safely connected to or disconnected from the main busbar of a Ring Main Unit (RMU), enabling distribution to secondary substations or large consumers. -
How does the "shielded front connector" improve safety?
The connector is entirely enclosed by a grounded metal shield. This contains the electrical field, prevents accidental contact with live parts, suppresses partial discharges, and protects against environmental contaminants, making live-line work areas significantly safer. -
Can this branch box be used with both SF6 and air-insulated switchgear?
It is primarily designed for compatibility with gas-insulated (SF6) ring main units, which are common for 35KV applications. Compatibility with specific air-insulated equipment should be verified based on the interface dimensions and ratings. -
What are the standard and optional earthing features?
A manual earthing switch is typically standard, allowing the cable side to be safely earthed for maintenance. Options may include a motorized earthing mechanism or additional safety interlocks that prevent plug removal unless the circuit is earthed. -
What is the typical delivery lead time for this product?
Lead times vary based on order quantity and specific configuration. Standard models may have shorter lead times, while customized versions (specific current ratings, special coatings) require additional engineering and production time. Please inquire for an accurate schedule. -
Are spare parts and technical support readily available?
Yes, as the manufacturer, we maintain an inventory of critical spare parts like plug-in contacts, shields, and gaskets. We provide comprehensive technical documentation and support for installation and maintenance procedures. -
What environmental conditions is the enclosure rated for?
The enclosure is generally constructed to meet at least IP65 (dust-tight and protected against water jets), making it suitable for outdoor installation in most climates. Higher protection levels (IP67) are available upon request for extreme environments. -
Is on-site installation supervision or training provided?
We can arrange for qualified engineers to provide on-site supervision for the first installation and conduct training sessions for your technical staff on safe operation and routine maintenance, subject to prior agreement.
