Description

Insulators are commonly used as a flexible coating on electric wire and cable. Since air is an insulator, in principle no other substance is needed to keep power where it should be. High-voltage power lines commonly use just air, since a solid (e.g., plastic) coating is impractical. However, wires which touch each other will produce cross connections, short circuits, and fire hazards. In coaxial cable the center conductor must be supported exactly in the middle of the hollow shield in order to prevent EM wave reflections. Finally, wires which expose voltages higher than 60V can cause human shock and electrocution hazards. Insulating coatings help to prevent all of these problems.

Feature

The Toughened glass insulators of cap and pin type is used high-voltage, ultrahigh voltage and extra high voltage alternating current and direct current transmission lines and hanging wires. It consists of iron cap, toughened glass and insulator pin. And owing to light weight, high intensity and large creepage distance , it can save metallic materials and reduce line cost.
