\u4ea7\u54c1\u6982\u8ff0<\/h2>\n\n\n\n

The 35kV-130\u00d7320 High-Voltage Sensor<\/a>, corresponding to the model CG5-35Q\/130\u00d7320<\/strong>, is an epoxy resin cast capacitive sensor<\/a> designed for 35 kV indoor high-voltage electrical systems.<\/p>\n\n\n\n

The product integrates three core functions: voltage presence indication, electrical interlocking against incorrect operation, and post-insulator support. It is widely used in high-voltage switchgear, ring main units, and other complete electrical equipment and is a key component for ensuring the safe operation of power distribution systems.<\/p>\n\n\n\n

\u4ea7\u54c1\u7279\u70b9<\/h2>\n\n\n\n

Excellent Insulation Performance<\/h3>\n\n\n\n

The sensor is manufactured from high-quality epoxy resin using an integrated vacuum-casting process. Its optimized shed structure increases the creepage distance and improves electric field distribution.<\/p>\n\n\n\n

The product provides high dielectric strength, arc resistance, corona resistance, and a low partial discharge level of no more than 5 pC. It can withstand system overvoltage and helps reduce the risk of electrical flashover.<\/p>\n\n\n\n

\u96c6\u6210\u7ed3\u6784\u8bbe\u8ba1<\/h3>\n\n\n\n

The capacitive voltage-sensing rod and \u67f1\u5f0f\u7edd\u7f18\u5b50<\/a> are integrated into a single structure. The sensor can replace a conventional \u67f1\u5f0f\u7edd\u7f18\u5b50<\/a> in compatible applications without requiring an additional insulating support.<\/p>\n\n\n\n

This integrated design simplifies the internal switchgear structure, reduces installation space, and provides high mechanical strength with reliable resistance to vibration and impact.<\/p>\n\n\n\n

Reliable Interlocking Protection<\/h3>\n\n\n\n

The sensor extracts a voltage signal from the high-voltage circuit and supplies it to the voltage presence indicator and electromagnetic interlocking system.<\/p>\n\n\n\n

It can provide forced interlocking for switchgear operating handles, access doors, mesh doors, and earthing switches. As long as the high-voltage circuit remains energized, the interlocking function remains active, helping prevent accidents caused by incorrect operation.<\/p>\n\n\n\n

The indication and interlocking circuits operate independently and do not interfere with each other.<\/p>\n\n\n\n

\u5f3a\u5927\u7684\u73af\u5883\u9002\u5e94\u6027<\/h3>\n\n\n\n

The epoxy resin material provides reliable resistance to ageing, heat and humidity, contamination, and electrical tracking.<\/p>\n\n\n\n

Its hydrophobic insulating surface supports stable operation across a temperature range of -35\u00b0C to +40\u00b0C, making the sensor suitable for most indoor high-voltage distribution environments.<\/p>\n\n\n\n

\u514d\u7ef4\u62a4\u8bbe\u8ba1<\/h3>\n\n\n\n

The fully sealed cast structure contains no exposed live parts and provides reliable protection against moisture, dust, and condensation.<\/p>\n\n\n\n

Under normal operating conditions, the sensor requires minimal routine maintenance and offers a long service life.<\/p>\n\n\n\n
