Electrical insulators; of glass

HS code 854610 covers the classification of electrical insulators made of glass. These insulators play a vital role in the electrical and electronics industry, ensuring the safe and efficient transmission of electrical current by preventing short circuits and leakage. As a critical component in a wide range of electrical equipment and infrastructure, the demand for high-quality glass insulators is driven by the ongoing expansion and modernization of power grids, telecommunications networks, and industrial automation systems worldwide.

The production of glass electrical insulators typically involves a multi-step process. First, raw materials such as silica sand, soda ash, and limestone are carefully measured and mixed to create the desired glass composition. The mixture is then melted in a high-temperature furnace, and the molten glass is formed into the desired insulator shape using techniques like pressing, blowing, or casting. Finally, the insulators undergo annealing, a controlled cooling process, to ensure their structural integrity and durability.

The main inputs required for the production of glass electrical insulators include 2505 Silica sand, 2511 Limestone, 2801 Soda ash, and various other mineral additives that contribute to the specific properties of the glass. Additionally, specialized machinery and equipment, such as furnaces, molds, and annealing ovens, are essential for the manufacturing process.

The primary output of HS code 854610 is a wide range of glass electrical insulators, which are used in various applications, including power transmission and distribution lines, electrical transformers, switchgear, and telecommunications equipment. These insulators are often consumed by industries covered under 8501 Electric motors and generators, 8535 Electrical apparatus for switching or protecting electrical circuits, and 8536 Electrical apparatus for switching or protecting electrical circuits, for a voltage not exceeding 1,000 V.
