Product Description

1. Introduction to 35kV Front Connector

   In the 35kV medium - voltage power distribution system, the 35kV front connector, as a key component, is of great significance for ensuring the stability and safety of power transmission. It is often used for the incoming and outgoing line connections of electrical complete cabinets, such as cable distribution boxes, ring - main unit switchgear and other complete equipment.

   I. Design and Structure

2. Insulating Material: It is made of high - performance silicone rubber or ethylene - propylene - diene monomer (EPDM) rubber. These materials are resistant to ozone, weather, and can withstand strong electrical stress, ensuring long - term stable operation even in harsh environments. For example, in outdoor environments with high humidity and strong ultraviolet rays, it can still maintain good performance.
3. Conductive Components: Mainly made of high - purity copper or copper - alloy materials, their low resistivity can effectively reduce power loss during current transmission, making power transfer more efficient.
4. Stress Control Design: Advanced stress control technology is applied to evenly disperse the electric field around the connection area, reducing the risk of partial discharge and electrical breakdown, and greatly enhancing the safety and reliability of the connection.

IV. Safety Features

Full Insulation and Sealing: The connector is fully insulated and well - sealed, which can prevent accidental electric shock and block moisture, dust, and other pollutants. It is suitable for various indoor and outdoor environments, including high - humidity or dusty industrial areas. Grounding Function: It is equipped with a reliable grounding mechanism. In the event of a fault or abnormal current, it can quickly divert the over - current to the ground, protecting equipment and personnel safety and maintaining the stability of the power system.

III. Installation and Application

Installation Process: The installation operation is relatively simple. It can be easily inserted and connected to the matching sockets of ring - main units (RMUs), cable branch boxes, or switchgear. A locking mechanism is used to ensure a tight and stable connection, guaranteeing safe operation. Application Scenarios

• Power Distribution Network: Widely used in urban and rural power distribution networks, it is used to connect the power cables at various distribution points, facilitating grid maintenance, repair, and network reconfiguration.
• Industrial Field: In industrial places such as factories and refineries, where medium - voltage power is relied on to drive large - scale mechanical equipment, the 35kV front connector can ensure a reliable power supply.
• Renewable Energy Facilities: In renewable energy projects such as wind farms and solar power plants, it is used to connect power generation equipment to the grid, helping to integrate renewable energy into the existing power distribution network.

II. Performance Characteristics

Voltage Rating: With a rated voltage of 35kV, it is specifically designed for the 35kV medium - voltage power distribution system. It can withstand the normal operating voltage of the system and possible transient over - voltages, ensuring a stable power supply. Current - Carrying Capacity: The common rated current - carrying capacity is 630A, and some models are even higher, which can meet the large - current demands of various electrical equipment and distribution lines. Insulation Performance: It has excellent insulation performance and can pass high - voltage tests far exceeding the rated voltage. For example, the 1 - minute power - frequency withstand voltage test can reach about 70kV. At the rated voltage, the partial discharge quantity is extremely low, usually less than 10pC, which effectively maintains the integrity of the insulation system and prevents electrical failures.
