Spool insulators are a type of electrical insulator that is mostly used to support and insulate different types of wires and cables. They are mostly made of made of porcelain or glass and have a cylindrical or spool-like shape, which is where their name came from. These electrical insulators are designed to withstand high voltages and provide a reliable and durable insulation solution for electrical systems.
Spool Insulator Prices
Spool insulator prices can vary depending on the material and the number of spoons. On average, its price can range between ₱155.00 to ₱690.00.

Advantages of Spool Insulator
Electrical Insulation – Spool insulators provide effective electrical insulation which helps prevent current leakage and ensures the safe and reliable operation of electrical systems.
Mechanical Strength – These insulators are designed to withstand mechanical stresses without a hint of breaking or deforming, making them suitable for supporting overhead lines and other structures.
Weather Resistance – The weather resistance of spool insulators ensures their durability and longevity even if they are used in outdoor applications.
Versatility – These insulators come in various sizes and materials, allowing users to choose the right one that fits a specific application/ This trait is highly valued in industries that deal with electrical and telecommunications networks.
Cost-Effective – Spool insulators are cheaper when you compare them to other insulator varieties which makes them the more practical choice to be used in various applications.
Disadvantages of Spool Insulator
Brittleness – One disadvantage of spool insulators, especially those that are made from porcelain is that they can be brittle and prone to cracking or breaking under impact or excessive mechanical stress. This brittleness of theirs can compromise their effectiveness and lead to failure in electrical systems
Weight – Spool insulators, especially porcelain ones, can be heavy, which can make handling and installation challenging, particularly in overhead applications where weight is a concern.
Cost – Porcelain spool insulators are more expensive than their polymer counterparts, which can impact the overall cost of electrical system installations or upgrades.
Installation Complexity – Installing spool insulators in overhead power lines or electrical distribution systems can be complex and may require specialized equipment and training.
