As a professional manufacturer with a commitment to quality and innovation, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our advanced European T-type Plug and Drop 35KV Ring Main Unit (RMU). Designed for reliability and operational safety in modern secondary distribution networks, this unit integrates a touchable shielded front connector, a feature that significantly enhances operator protection and system integrity. Our focus on stringent manufacturing processes, supported by a robust quality management system, ensures that this RMU delivers consistent performance for utilities and industrial clients worldwide, helping to secure power distribution in diverse environments from urban centers to remote installations.
This Ring Main Unit represents a sophisticated solution for medium-voltage switchgear applications. Its core design philosophy revolves around safety, modularity, and ease of maintenance.
- Touchable Shielded Front Connector: The defining feature of this RMU is its front connector with a touchable shielded design. This innovation allows for safer cable connection and disconnection procedures by providing an extra layer of insulation and physical protection, reducing the risk of accidental contact with live parts during routine operations.
- T-type Plug and Drop System: Utilizing a European-standard T-type plug-in interface, this RMU enables swift and tool-less installation or replacement of functional modules like circuit breakers, switches, and fuse combinations. This plug-and-drop functionality drastically reduces outage times during maintenance or network reconfiguration.
- Compact and Modular Construction: Engineered for space-saving installations, the unit's compact design is ideal for substations with limited footprint. Its modular architecture allows for flexible configurations (2-way, 3-way, or 4-way) to meet specific project requirements, facilitating future expansion.
- Enhanced Safety and Reliability: The unit is typically filled with SF6 or dry air as an insulation and arc-quenching medium, ensuring high dielectric strength and operational safety. The sealed tank design maintains pressure integrity, contributing to long service life and minimal maintenance needs.
- Superior Protection Level: Critical areas, such as cable connections and bushings, are designed to achieve a high Ingress Protection (IP) rating, typically IP67, safeguarding internal components against dust and water ingress for reliable operation in harsh outdoor conditions.
The technical specifications highlight the unit's capability and design parameters. Key specifications are summarized below:
| Parameter | Specification |
|---|---|
| Rated Voltage | 35 KV |
| Rated Frequency | 50 / 60 Hz |
| Rated Normal Current | 630A, 1250A (typical) |
| Short-Time Withstand Current | 25 kA / 3s (typical) |
| Insulation Medium | SF6 or Dry Air (optional) |
| Operating Mechanism | Spring-operated, Motor-operated (optional) |
| Connection Type | T-type Plug-in (Front Access) |
| Degree of Protection (IP) | IP67 (bushing area) |
For clients, the benefits are substantial. The touchable shielded connector directly translates to a safer working environment for field technicians, reducing training requirements for high-risk tasks. The plug-and-drop modularity minimizes system downtime, leading to lower operational costs and improved network availability. Furthermore, the unit's robust design and adherence to international electrical standards ensure long-term reliability, protecting your infrastructure investment. Its compatibility with various automation and monitoring systems allows for integration into smart grid applications, future-proofing your distribution network.

Frequently Asked Questions (FAQ)
-
What is the primary advantage of the "touchable shielded" front connector?
This design provides an additional physical and insulated barrier around the live connection points. It enhances operator safety during cable mating/unmating by significantly reducing the risk of accidental direct contact, allowing for procedures to be performed with greater confidence and potentially under less restrictive safety protocols. -
Is this RMU compatible with existing switchgear from other manufacturers?
Compatibility depends on the specific interface and standards used in your existing setup. The "European T-type" plug-in system is a standardized interface. We recommend providing detailed specifications of your current equipment for our engineering team to verify compatibility or suggest suitable adaptation solutions. -
What are the maintenance requirements for this SF6-insulated RMU?
Modern sealed-pressure SF6 RMUs are designed for minimal maintenance. Primary checks involve periodic visual inspection, verifying pressure gauges (if equipped), and mechanical operation tests. Major internal maintenance intervals are typically very long (e.g., 20+ years), contingent on operating conditions and number of operations. -
Can this unit be supplied with a motor-operated mechanism for remote control?
Yes, a motor-operated mechanism is available as an optional feature. This enables remote opening and closing of switches or breakers, facilitating integration into SCADA (Supervisory Control and Data Acquisition) systems and unmanned substation operations. -
What configuration options are available (2-way, 3-way, etc.)?
The unit is modular and can be configured as 2-way, 3-way, or 4-way ring main units according to your network topology needs. Custom configurations with specific combinations of switches, circuit breakers, and cable entries can also be discussed based on project requirements. -
What is the typical delivery lead time for an order?
Lead times vary based on order quantity, configuration complexity, and current production schedule. Standard configurations typically have shorter lead times. We provide estimated timelines upon receipt of your detailed specifications and can often accommodate urgent requests. -
Are spare parts readily available for long-term support?
As the manufacturer, we maintain an inventory of critical spare parts like plug-in modules, operating mechanisms, and seals. We provide comprehensive after-sales support and can guarantee the availability of spare parts for the declared service life of the product. -
What standards does this product comply with?
The RMU is designed and tested in accordance with common international standards for medium-voltage switchgear, such as the IEC 62271 series. Specific test reports and certificates for parameters like rated short-circuit breaking capacity can be provided upon request.
