Product Description

1. 35kV Rear - mounted Plug - in Connector Introduction

   The 35kV rear - mounted plug - in connector is a crucial component in medium - voltage power distribution systems, playing a significant role in ensuring the stable connection and reliable operation of power cables.

   I. Design and Structure

   1. Insulating Material

   • It is crafted from high - performance insulating materials, typically silicone rubber or EPDM (Ethylene - Propylene - Diene Monomer) rubber. These materials possess excellent resistance to environmental factors such as ozone, moisture, and extreme temperatures. For instance, in areas with high humidity or frequent temperature fluctuations, the connector can still maintain stable insulation performance. The material also has good electrical insulation properties, effectively preventing electrical leakage and ensuring the safety of the power system.

   1. Conductive Parts

   • The conductive elements of the 35kV rear - mounted plug - in connector are mainly made of high - purity copper or copper - alloy materials. These materials have extremely low resistivity, which is beneficial for minimizing power loss during the transmission of high - voltage and high - current electricity. As a result, they can ensure efficient power transfer and improve the overall efficiency of the power distribution system.

   1. Stress Control Design

   • Advanced stress control technology is integrated into the design. This technology is designed to evenly distribute the electric field around the connection area of the connector. By doing so, it significantly reduces the risk of partial discharge and electrical breakdown. For example, through the optimization of the shape and material distribution of the stress - control layer, the electric field intensity at critical points can be effectively reduced, thereby enhancing the reliability and safety of the connection.

   II. Performance Characteristics

   1. Voltage Rating

   • Rated at 35kV, this rear - mounted plug - in connector is specifically engineered for use in medium - voltage power distribution systems operating at this voltage level. It can withstand not only the normal operating voltage of 35kV but also transient over - voltages that may occur in the power grid. These over - voltages could be caused by lightning strikes, switching operations, or other electrical disturbances. The connector's ability to handle such voltage fluctuations ensures the stable operation of the power system.

   1. Current - Carrying Capacity

   • It usually has a rated current - carrying capacity of 600A or 630A, depending on the specific model and design. This capacity enables it to meet the substantial current demands of various electrical equipment and distribution lines in industrial plants, commercial buildings, and power distribution networks. For example, in a large - scale industrial factory where multiple high - power motors and equipment are operating simultaneously, the 35kV rear - mounted plug - in connector can effectively carry the required current to ensure the normal operation of these devices.

   1. Insulation Performance

   • The connector exhibits outstanding insulation performance. It can pass a 1 - minute power - frequency withstand voltage test at a voltage much higher than the rated value, typically around 70kV. Additionally, at the rated voltage of 35kV, the partial discharge level is kept extremely low, usually less than 10pC. This excellent insulation performance is crucial for maintaining the integrity of the insulation system, preventing electrical failures, and ensuring the long - term and stable operation of the power system.

   III. Installation and Application

   1. Installation

   • The installation process of the 35kV rear - mounted plug - in connector is relatively straightforward. It can be easily inserted into and firmly connected to the corresponding mating socket, which is often found in ring - main units (RMUs), cable branch boxes, or switchgear. A reliable locking mechanism is usually employed to ensure a tight and stable connection during operation. This not only simplifies the installation work but also guarantees the safety and reliability of the connection in the long run.

   1. Applications

   • Power Distribution Networks: Widely used in both urban and rural power distribution networks, the 35kV rear - mounted plug - in connector is used to connect power cables at various distribution points. It allows for convenient maintenance, repair, and network reconfiguration. For example, when there is a need to upgrade or modify a power distribution line, the connector can be easily disconnected and re - connected, minimizing the impact on power supply.

   • Industrial Settings: In industrial plants, refineries, and other industrial facilities that require medium - voltage power to drive large - scale machinery and equipment, these connectors are essential for ensuring a stable and reliable power supply. They can be used to connect power - intensive equipment such as large motors, compressors, and industrial furnaces to the power grid.

   • Renewable Energy Installations: With the rapid development of renewable energy sources such as wind farms and solar power plants, 35kV rear - mounted plug - in connectors are used to connect the power generation equipment to the grid. They play a key role in integrating renewable energy into the existing power distribution infrastructure, promoting the transition to a more sustainable energy future.

   IV. Safety Features

   1. Full - Insulation and Sealing

   • The 35kV rear - mounted plug - in connector is designed to be fully insulated and well - sealed. This not only protects against accidental electrical contact but also prevents the ingress of moisture, dust, and other contaminants. As a result, it can be safely used in both indoor and outdoor environments, including harsh conditions such as high - humidity coastal areas or dusty industrial sites.

   1. Grounding Function

   • It is equipped with a reliable grounding mechanism. In the event of a fault or abnormal current situation, the grounding system can quickly divert the excessive current to the ground. This protects the equipment and personnel from electrical hazards, ensuring the safety of the entire power system. For example, if there is a short - circuit in the connected equipment, the grounding mechanism of the connector will immediately direct the fault current to the ground, preventing damage to the equipment and reducing the risk of electric shock.

   In conclusion, the 35kV rear - mounted plug - in connector is an essential component in medium - voltage power distribution systems, offering reliable performance, easy installation, and high - level safety features. Its wide range of applications makes it a key element in maintaining the efficient and stable operation of power systems.
