Introduction to the bypass non-power-off comprehensive operation system
The bypass non-power-off comprehensive operation system is an emerging technology that improves the reliability of power supply in distribution networks. It includes various operation methods such as routine operations, live working, bypass operations, and mobile power operations. It utilizes flexible bypass power cables, quick plug cable heads, bypass load switches, and live working vehicles to form different distribution units, providing users with bypass non-power-off power supply. It allows distribution operation personnel to complete planned maintenance work on lines without interrupting power supply, and also enables temporary power supply for difficult-to-handle overhead lines and cable line faults, reducing the scope of power outages and minimizing the impact on users.
Core equipment of the bypass non-power-off comprehensive operation system
1Bypass flexible circuit cable
Bypass flexible circuit cable is a special power cable with a special rubber insulation layer, tinned annealed soft copper conductor as the core, and a shielding layer made of tinned copper wire and fiber mixed weaving. Its characteristics include a small bending radius, ease of storage, and reusability.

Product features
◇The conductor is made of twisted tinned annealed soft copper wire, with a conductor cross-section of 50mm, and 708 strands of 0.30.
◇The insulation is made of ethylene propylene rubber, with a nominal thickness of 4.5mm.
◇The shielding layer is made of tinned copper wire and fiber mixed weaving. The cross-sectional area of the copper wire is 10mm.
◇The outer sheath is made of neoprene rubber, with a nominal thickness of 2.0mm.
◇The nominal outer diameter of the cable is 29.3mm, and the bending radius of the cable is 6 times the outer diameter of the cable.
◇The maximum pulling force during cable laying is 3500N.
2Bypass quick plug cable head
The bypass quick plug cable head can quickly complete the electrical connection with bypass cable equipment and the conversion with conventional lines, while maintaining continuous insulation, forming a temporary bypass cable power supply line. It features a quick plug-in self-locking function, making operation safe and simple.
