Running plays a vital role.
2, use of Fully insulated aluminum bus tube
It is mainly used in the conductor connection between transmission line and transformer substation in China's electric power construction engineering, the jumpers and power in the transmission line
The connection conductor in the equipment and the over-current conductor in the high-current DIRECT current ice melting device replace the traditional rectangular, groove, bar shaped busbar and flexible conductor
Volume conductor plays a vital role in the safe and reliable operation of power transmission and transformation system and power equipment.
3, performance of Fully insulated aluminum bus tube
This series product has the unique material property structure form and the processing craft, has many technical patents, is a kind of new energy-saving bus conductor
Material, is the traditional steel core aluminum strand, groove, rectangular aluminum bus substitute products.
The main performance is as follows:
1) Tubular conductor (bus) adopts a series of advanced technologies such as advanced hot-top casting seamless pipe, with smooth surface, high dimensional accuracy and tensile strength
High degree, not easy to produce discharge and deformation;
2) The products are made of rare earth and heat-resistant aluminum alloy with good processing, welding, electrical conductivity and heat-resistant properties;
3) Good convection heat dissipation condition, low temperature rise, small loss, strong conductive capacity, large carrying capacity;
4) High heat resistance, conductor has high mechanical strength at high temperature, improve the safety and reliability of power transmission and transformation system;
5) Installation covers a small area, and the combined pipe bus is covered by flexible wires
A third;
6) Corrosion resistance, not easy to cover ice, strong disaster resistance, long service life;
7) Convenient installation, beautiful appearance, safe, stable, reliable and convenient operation
Repair and maintenance.
4. Technical requirements
1) The nozzle is flat and perpendicular to the axis.
2) The tube bus length deviation is a positive error: +15~+25mm
3) Straightening spiral marks and their depth are allowed on the tube bus without affecting the outside diameter
No more than 0.5 mm
4) Bending degree of tube bus: m/L < 2.0mm
5) The spacing between tube mother and matching liner shall be no more than 0.5mm and safety shall be guaranteed
Need to be.
6) The bus surface is smooth and smooth, without cracks, creases, inclusions and deformation
Distortion phenomenon.
7) Elastic modulus value to control the deflection value after installation within the specified range.
