Porcelain Stay Insulators

Product Description

Porcelain Stay Insulators, Porcelain Insulators in The Stay Wire

Porcelain Stay Insulators, also known as low voltage insulators, stay type insulators, or egg insulators, are used to provide electrical insulation and mechanical support in overhead power lines. To prevent the dead end pole or terminal pole from falling down, it is essential to select the appropriate types of stay insulators and pole line fittings. Yipeng stay insulators are designed to prevent accidental electric conduction on the stay wire. Yipeng is a Leading manufacturer of power line insulators, offer types of stay Insulators, provide support on design, fabrication, evaluation and installion.

How does a stay insulator function?

The stay insulator body has two holes, through which two guy grips pass in opposite directions. The guy grips wrap around the stay wire to create the connection.

The method of connection can vary by market, with different regions having different connection practices. As an insulator manufacturer and supplier, we can also design insulator fittings according to customers' designs and drawings.

Stay Insulator

According to the voltage, there are 11kv stay insulators and 33kv stay insulator 11kv stay insulator is used on the 11kv overhead line network in the power system. Yipeng stay insulator is used to connect the stay wire or guy wire.

Yipeng stay insulator is made of glazed porcelain according to BS137 and suitable for operation outdoors. The working condition for the 11kv stay insulator is as below :

Normal system voltage 11kv

System highest voltage 12.5kv

50 cycles dry flash over 40kv

50 cycles wet flash over 22kv

Leakage distance 80mm

Tensile strength 90kn
