SMC Fiberglass Street Armor – A Revolutionary Protective Solution for Porcelain Insulators


In the quest for reliable electrical infrastructure, innovative solutions are constantly sought to ensure the safety and integrity of power lines. Among these solutions is the SMC Fiberglass Street Armor, an exceptional product designed to protect porcelain insulators used in stringing electrical cables. With its unique manufacturing process, versatile applications, and outstanding performance benefits, this armor has revolutionized the way we secure our electrical systems.

Manufacturing Process:

The SMC (Sheet Molding Compound) Fiberglass Street Armor is fabricated using a specialized molding process that involves layering fiberglass mats with resin to create a composite material. This process begins with the careful selection of high-quality fiberglass mats that offer superior strength and durability. These mats are then saturated with a precise amount of thermosetting resin, ensuring a consistent and thorough mixture.

Once saturated, the fiberglass mats are placed into a mold preheated to a specific temperature. The molding press then applies high pressure to the mats, compressing them and forcing the resin to flow through the fibers, creating a dense and strong structure. The heat initiates the curing process of the resin, which solidifies and bonds with the fiberglass to form the final product.

Following curing, the fiberglass street armor is removed from the mold and undergoes trimming and finishing processes to achieve the desired shape and smooth surface. Quality control checks are performed to ensure each piece meets the stringent standards set for electrical industry use.


SMC Fiberglass Street Armor is primarily designed for use in overhead power line installations where it plays a critical role in protecting porcelain insulators during stringing operations. These insulators are essential components that isolate conductors from the supporting structures to prevent short circuits and maintain system integrity.

Available in both 2 and 4-position configurations, the armor caters to different installation requirements. The 2-position design is ideal for standard applications, while the 4-position option provides additional support for more complex or high-tension setups. The armor can be easily installed onto existing poles or structures, providing a secure platform for the insulators without the need for extensive modifications.
