Product Details
SRML (Silicone Rubber Motor Lead) wire is a specialized high-temperature electrical wire primarily applied where extreme heat, flexibility, and durability are paramount. Its main uses include motor lead wire, connecting power to electric motors, particularly in industrial or hazardous settings. SRML is suitable in demanding industrial environments and power generation equipment where wiring faces repeated movement, abrasion, or exposure to oils, chemicals, and moisture, making it a go-to solution for reliable performance under severe thermal and environmental stress. Silicone rubber is halogen free and is very flexible while the fiberglass braid provides good mechanical strength.

APPLICATIONS:
Motor lead wire, ovens, furnaces, kilns, heating elements, stoves, washing machines and various lighting fixtures.

TEMPERATURE RATING:
150ºC / 302ºF

AWG, or American Wire Gauge, is the standard system used primarily in North America to measure the diameter of electrical conductors. This system is critical because a wire's size directly impacts its electrical resistance and how much current (ampacity) it can safely carry. A key principle is that the smaller the AWG number, the larger the wire's diameter; for instance, 12 AWG is thicker and can carry more current than 14 AWG. Sizes beyond 0 AWG are referred to as "aught" (e.g., 1/0, 2/0). Selecting the correct AWG is essential for safe electrical installations, preventing overheating, and minimizing voltage drop.
Voltage drop is the natural reduction in electrical potential that occurs as current travels through a circuit, from the power source to a device. This happens because all wires inherently have resistance, which converts some electrical energy into heat, leading to a loss of voltage. While minor voltage drop is normal, excessive amounts can cause problems like dimming lights, slow or overheating motors, and erratic electronic behavior. It can also lead to higher energy consumption and, in severe cases, create safety hazards due to overheating wires. Key factors influencing voltage drop include the wire's length and thickness (gauge), the amount of current flowing through it, and the quality of electrical connections.
In electrical wiring, amps (amperes) measure the rate of electrical current flow. Think of it as the volume of electricity moving through the wire at any given time. Crucially, every electrical wire has an ampacity rating, which is the maximum current it can safely carry continuously without overheating. Exceeding a wire's ampacity can lead to insulation damage and fire hazards, highlighting why proper wire sizing based on expected amperage is vital for safe electrical systems.
A wire's ampacity, or its safe current-carrying capacity, changes with temperature primarily because of two factors. First, the electrical resistance of copper and aluminum wires increases as they get hotter, causing them to generate more heat when current flows. Second, every wire's insulation has a maximum temperature limit; exceeding this can cause degradation and safety hazards. Therefore, in hotter environments, a wire must carry less current to avoid exceeding its insulation's temperature rating. This ensures the wire remains safe and functional, preventing overheating and potential failures.
We aim to provide authentic, precise images of each wire; however, with various product variations, it can be challenging. In such instances, we focus on showcasing the fundamental design. Always refer to the product specifications rather than relying solely on images.
