The steps and requirements for installing fully insulated tubular busbar electrical equipment. The fully insulated tube type busbar uses hollow copper tubes as conductors, with a thermal insulation layer, pressure equalization shielding layer, insulation waterproof layer, grounding shielding layer, external insulation protection tube layer, and UV resistant insulation three color protection on the outer surface. During installation, it can be directly fixed on steel structure frames or concrete supports, eliminating wall sleeves and post insulators, and has strong seismic resistance. The busbar structure is simple, the layout is clear, easy to install, and does not require maintenance. So, what are the steps and requirements for installing fully insulated tubular busbar electrical equipment?

All metal components exposed to the atmosphere are made of materials with reliable rust prevention layers. When installing on site, please round the copper tube end of the insulated tube busbar and silver or tin the connection surface of the copper tube end to ensure low contact resistance and corrosion resistance.

2. Intermediate joint requirements: The joint should meet the requirements of flow rate and temperature rise. The insulation structure at the joint should be the same as that of the tubular busbar, and the insulation surface potential at the joint should be zero to ensure the safety of operation and maintenance

3. Terminal connectors require the use of copper flexible connections between insulated copper tube busbars and equipment.

4. Grounding requirements: The shielding of solid-state insulated tube bus capacitors must be reliably grounded, including the shielding insulation sleeve at the intermediate joint. The grounding method is one point grounding (which can be partially grounded) to avoid grounding of the insulated pipe busbar. Due to the multi-point grounding of the wires, circulating currents are generated to ensure that the external grounding screen can meet the requirements for safe human touch.

5. On site acceptance requirements for fully insulated tube busbars: When inspecting and accepting insulated tube busbars, their surfaces should be smooth and free of scars, and the main insulation resistance should not be less than 15000M Ω· m.
