Applications and types of electrical insulators: electrical insulators are widely used in the design and manufacture of electrical equipment and machines. Their main function is to prevent unwanted current flow and maintain device safety and performance. These insulators are made from diverse materials, each with its own properties and applications.
Electric Motors and Generators:
Electric motors: these motors are designed to convert electrical energy into mechanical energy. The electrical insulation used in these motors must have high resistance to heat, stress, and vibration. Materials such as mica, insulating paper, and polyester films (such as PET) are among the most common insulating materials in these motors. Mica, due to its high heat resistance and excellent dielectric properties, is used in motor windings. Generators: generators convert mechanical energy into electrical energy, and in this process, electrical insulators are essential for separating windings and preventing short circuits. Polyester films and insulating paper with low moisture absorption and heat resistance are among the materials used in generators.
Transformers:
In transformers, electrical insulation is used to separate the primary and secondary windings. In addition to high dielectric strength, these insulators must withstand electrical and thermal stresses. Specialized insulating papers, insulating oils, and epoxy resins are among the materials used for transformer insulation.
Cables and Wires:
Power cables and wires are coated with electrical insulation to prevent current leakage and potential hazards. Insulating materials such as PVC, XLPE (cross-linked polyethylene), and silicone rubber are commonly used for this purpose. In addition to dielectric properties, these materials must also provide good resistance to environmental factors such as moisture, heat, and chemicals.
2) Properties and Applications of Silicone Insulators
Properties and applications of silicone insulators: silicone insulators are recognized as one of the most popular insulating materials across industries due to their unique characteristics such as high heat resistance, flexibility at both low and high temperatures, and resistance to harsh environmental conditions.
Electronics Industry:
Silicone insulators are widely used in the electronics industry. Thanks to their high dielectric properties and heat resistance, they are ideal for insulating sensitive electronic components such as printed circuit boards, sensors, and transistors. Silicone is also used as a protective coating in electronic circuits and sensitive wires due to its flexibility and resistance to aging.
Automotive Industry:
In automotive, silicone insulators are used to protect wires and electrical components exposed to high temperatures, chemicals, and severe vibrations. They are especially used where insulation against heat and moisture is required, such as engine electrical systems, ABS, and HVAC systems.
Construction:
In the construction industry, silicone insulators are used to produce various materials such as sealants, construction adhesives, and waterproofing insulations. Due to UV resistance, waterproof properties, and flexibility, silicone is known as an ideal material for sealing and insulating in building projects.
3) Professional Tips for Clearance + HS Code
Customs clearance of electrical and silicone insulators, due to the high sensitivity of these products in ensuring the safety and proper performance of electrical and electronic equipment, requires strict adherence to technical details, international standards, and valid documentation. Below are key points that must be considered during the clearance process:
Customs Tariff and HS Code
The customs tariff (HS Code) is one of the most important factors in clearing goods, helping to correctly classify products and determine import/export duties. Choosing the right HS Code for electrical and silicone insulators can significantly impact import costs and also prevent delays in the clearance process.
Electrical Insulators:
This product group generally falls under tariffs for electrical insulating parts and materials. For example, HS Code 85469000 relates to electrical insulators made of various materials, including mica, paper, polyester films, and similar materials. The precise code depends on the material type, end-use, and the insulator’s chemical composition.
In specific cases, more specialized HS Codes may be required for insulating materials used in specialized applications such as aerospace or medical equipment.
Silicone Insulators:
Silicone insulators are also classified under different tariff headings depending on product type and application. For example, HS Code 39269097 is used for plastic products made of silicone. This code covers various silicone products, including sealants, gaskets, and silicone electrical insulators.
Attention to the exact composition and specific properties of each silicone product—such as operating temperature range, UV resistance, and mechanical properties—can help in selecting a more accurate tariff code.
