1. 绝缘与电气性能

• Utilizes an integrated epoxy resin vacuum casting process, ensuring a void-free and bubble-free structure with stable insulation performance. It withstands the rated voltage and short-duration overvoltage of 10kV systems, maintaining an ample insulation margin.
• Features stable capacitive characteristics and high compatibility with live-line indication devices, enabling accurate sensing of the circuit’s live status without the risk of false positives or missed detections.
• Meets high-altitude design requirements; the insulation structure is optimized for low-pressure environments found at high elevations to prevent insulation failures such as corona discharge and flashover.

1. 机械与结构特性

• Features an integrated shed (skirt) design that increases creepage distance and enhances resistance to pollution flashover and moisture, making it suitable for complex indoor environments.
• Offers high mechanical strength and resistance to impact and vibration; it withstands mechanical stresses encountered during switchgear transport, installation, and operation without risk of cracking or deformation.
• Compact structure allows for easy installation; it fits standard mounting dimensions for 10kV indoor high-voltage switchgear, ensuring strong compatibility.

1. 环境适应性

• Excellent weather resistance; operates reliably across a wide temperature range (-40°C to +70°C) without degradation of insulation or mechanical properties.
• Resistant to moisture, mold, and salt spray, ensuring stable long-term operation in harsh indoor environments characterized by high humidity or dust.
• High-altitude models are optimized for elevations between 3,000m and 5,000m, meeting insulation and operational requirements for low-pressure environments. 4. Safety and Reliability
• Fully insulated structural design with no exposed live parts; eliminates the risk of electric shock to personnel and ensures safety during operation and maintenance.
• Long service life and maintenance-free; exhibits no aging or performance degradation during long-term operation; high reliability.
• Complies with national standards for high-voltage electrical equipment; passed type testing; safe and compliant.

V. Operating Conditions

1. 正常运行条件

• Altitude: Standard type ≤ 2,000m; high-altitude type 3,000m–5,000m;
• Ambient temperature: -40°C to +70°C; daily average temperature ≤ +35°C;
• Relative humidity: Daily average relative humidity ≤ 95%; monthly average relative humidity ≤ 90% (at 25°C);
• Environmental conditions: Free from severe pollution, corrosive gases, flammable or explosive media, and severe vibration or shock;
• Installation method: Vertical installation within the switchgear, with a reliable connection to the high-voltage busbar/conductor.

1. 特殊操作条件（需要定制）

• Altitude exceeding 5,000m;
• 环境温度超出-40°C至+70°C范围；
• Environments with severe pollution, salt spray, or chemical corrosion;
• Conditions involving strong vibration or severe shock;
• Special installation angles (non-vertical installation). VI. Installation and Maintenance

1. 安装要求

• Inspect the product’s exterior before installation; ensure there are no cracks, damage, or air bubbles, and that the insulation surface is intact;
• Install vertically within the switchgear cabinet; securely fasten the base using bolts to ensure a firm installation;
• Ensure a reliable connection between the top terminal and the high-voltage busbar/conductor, meeting contact resistance specifications;
• Use shielded and insulated wiring for the connection between the sensor and the live-line indicator to prevent interference;
• Conduct insulation resistance tests and power-frequency withstand voltage tests after installation; the product may only be put into operation after passing these tests.

1. 维护要求

• Periodically inspect the product’s exterior for cracks, discharge marks, or accumulated dirt;
• Periodically perform insulation resistance tests and power-frequency withstand voltage tests to ensure insulation performance meets standards;
• Clean the product surface to remove dust and contaminants, keeping the insulation surface dry and clean;
• Immediately take the product out of service and replace it if abnormalities such as cracks, damage, or discharge occur.

VII. Precautions

1. Installation, commissioning, and maintenance must be performed by qualified electrical personnel; operation by non-qualified personnel is strictly prohibited;
2. Before installation or maintenance, ensure the high-voltage circuit is completely de-energized and implement appropriate safety measures;
3. Products designed for high-altitude use must not be installed in areas exceeding their rated altitude range to prevent insulation failure;
4. Do not disassemble or modify the product without authorization; doing so will void the warranty and compromise safety;
5. During transport and storage, protect the product against moisture, vibration, and impact to prevent insulation damage.
