High-voltage silica gel insulating electric wire

Abstract

The invention discloses a high-voltage silica gel insulating electric wire, and belongs to the technical field of a cable electric wire. The high-voltage silica gel insulating electric wire comprisesa conductor; the high-voltage silica gel insulating electric wire is characterized in that the conductor is coated with glass fiber layers; the outer sides of the glass fiber layers are coated with adampproof layer; at least three arc-shaped silicone rubber layers are uniformly distributed between the glass fiber layers and the dampproof layer; and the arc-shaped silicone rubber layers are isolated by the glass fiber layers. The high-voltage silica gel insulating electric wire has the characteristic of high temperature resistance, high strength, dampproof property, and relatively high flexibility.

Description

technical field [0001] The invention belongs to the field of electricity, relates to the field of wires, in particular to a high-voltage silicone insulated wire. Background technique [0002] General wires and cables use plastic and rubber as insulating sheaths. These materials are conventional engineering materials with abundant sources, which can meet mass production, and the cost is relatively low. However, for some special industries such as petrochemical, steel, aerospace, shipbuilding, military industry, pharmaceuticals, food, plastic machinery, boilers and other industries related to heat and high temperature, wires and cables that can withstand a certain higher temperature are required. Cables are obviously unusable, and wires and cables with high temperature resistance are required to ensure the safe operation of their power and signals; silicone rubber wires have high heat resistance and excellent cold resistance, and their long-term use temperature range reaches -...

However, for some special industries such as petrochemical, steel, aerospace, shipbuilding, military industry, pharmaceuticals, food, plastic machinery, boilers and other industries related to heat and high temperature, wires and cables that can withstand a certain higher temperature are required. Cables are obviously unusable, and wires and cables with high temperature resistance are required to ensure the safe operation of their power and signals; silicone rubber wires have high heat resistance and excellent cold resistance, and their long-term use temperature range reaches -90°C-+250°C , which is the widest among all rubber wires, but its tensile strength is low, and its shear mechanical properties are poor
