Suspended porcelain insulator Introduction:

Suspended porcelain insulator usually consists of porcelain umbrella skirt, iron cap, steel foot and adhesive and other parts. Porcelain umbrella skirt is the main body of the insulator, with good insulating properties and a certain mechanical strength. Caps and feet are used to connect wires, fittings and towers to ensure that the insulator is firmly installed. The adhesive is used to firmly bond the porcelain umbrella skirt to the metal accessories to form an integral structure.

Suspended porcelain insulator Features:

Excellent insulating properties: Suspended porcelain insulators are made of high-quality porcelain material with excellent insulating properties and anti-aging properties, capable of maintaining stable insulating properties under harsh weather and environmental conditions.

High mechanical strength: the design of the insulator takes into account the mechanical and electrical loads of the line, and has sufficient mechanical strength to withstand the tension of the wire, wind and other external forces.

Good self-cleaning performance: some specially designed suspended porcelain insulators have excellent self-cleaning performance, which can reduce the accumulation of dust and dirt, and reduce the probability of dirt flash accidents.

Wide range of application: Suspended porcelain insulators are suitable for power lines of various voltage levels and degree of dirtiness, and can meet the needs of different regions and climatic conditions.

Suspended porcelain insulator Application:

Suspended porcelain insulators are widely used in high-voltage and ultra-high-voltage transmission lines, including power plants, substations and a variety of electrical equipment to support and insulate the external live conductors. In special environments (e.g. industrial dust, chemical, salt and alkali, coastal and foggy areas), pollution-resistant suspended porcelain insulators are widely used to ensure the stable operation of power systems.
