ED-2C Low Voltage Porcelain Ceramic Shackle Insulator

Short Description:

Low voltage butterfly insulator low-voltage distribution 0.4kV, bare conductor span 40 ~ 60m, insulated conductor span 30 ~ 50m. According to the above checking calculation, ED-1, ed-2 and ed-3 disc insulators are basically suitable for any low-voltage conductor. Considering the size of wire diameter, 25 ~ 35 bare wires and insulated wires use ed-3; 50 ~ 120 bare conductors and 50 ~ 95 insulated conductors use ed-2; Bare conductors of 150 and above and insulated conductors of 120 and above shall use ED-1.

Insulators are widely used devices, and their connecting fittings are also required to be interchangeable. In addition, the technical standards of butterfly insulators also require various electrical, mechanical, physical and environmental condition change tests on insulators according to different models and service conditions, as well as environmental condition change tests, so as to test their performance and quality.

Information

Low voltage line insulators are used for insulation and fixing of power line conductors with power frequency AC or DC voltage below 1KV. There are mainly needle type, screw type, spool type, tension and tram line insulator, etc. Butterfly and spool insulators can also be used for insulation and fixation of conductors on low-voltage line terminals, tension and corner rods. Tension insulator is used for insulation and connection of pole stay wire or tension conductor.

In the transmission line, the pole must bear the transverse (horizontal) tension of long straight section of wire. In order to bear this transverse tension, the construction party often uses tension insulators. In low-voltage lines (below 11kv), spool insulators are often used as tension insulators. However, for high voltage transmission lines, pin or disc insulator strings are required to be connected to the cross arm in the horizontal direction. When the tension load in the line is very high, such as at a long span, two or more insulator strings need to be used in parallel.

Product Information

Shackle insulators are divided into high-voltage Shackle insulators and low-voltage Shackle insulators.
