Epoxy resin casting insulated tubular busbar system
Epoxy resin cast insulated tubular busbar
It refers to the busbar with copper tube or aluminum tube as the conductor, epoxy resin pouring and filling between the protective tube and the conductor as the main insulation layer, and the surface potential is zero. Conductive or semi conductive conductive layer shall be arranged inside the main insulation to adjust the electric field distribution of the tubular busbar.
Epoxy resin casting insulated tubular busbar system
It is a system composed of epoxy resin cast insulated tubular bus body and its accessories and auxiliary devices, which can meet the connection and insulation requirements of electrical equipment.

As a new type of power transmission equipment that replaces the traditional rectangular bus, epoxy resin cast insulated tubular bus is essentially a bus product that uses copper or aluminum tube bus as conductor and external insulation. It has outstanding advantages such as high mechanical strength, large current carrying capacity, low surface field strength, good electrical insulation, strong environmental adaptability and small land occupation. It meets the needs of the development of various industries in the country. At present, it is widely used by substations It has been used in power plants, large-scale photovoltaic power generation projects, petroleum and petrochemical, steel, cement and other fields for decades.

 

This kind of bus was used in other types abroad in the early stage. In 2002, domestic enterprises began to introduce technology from Germany and completed type tests. On the basis of absorbing and learning from foreign advanced technology, our company has independently developed the epoch-making epoxy resin casting solid insulation tubular bus. Guangdong high-voltage tube type bus adopts normal temperature curing epoxy resin casting insulation layer. Theoretically, the withstand voltage per square millimeter can reach 20 ~ 30KV. The outer sheath layer adopts 8mm thick MPP power pipe to protect the main insulation layer from damage. Its shockproof and anti-collision ability is far higher than the ik10 specified in the national standard, and its protection grade reaches IP68. Its unique waterproof, fireproof, anti internal condensation performance and maintenance free characteristics have won wide market popularity and won the recognition and support of many owners.
