0.3mm Silicon Fiberglass Insulated Single/ Stranded Conductor High Temperature Heating Cable

General Description:

A high temperature, high tensile strength fiberglass, either color coded or with tracer yarn, is braided on both the single conductors and the overall jacket. Both are impregnated with a 500ºF modified resin saturant.

Cables can be installed in environments with harsh conditions and high ambient temperatures, but selecting the right cables for the correct environmental conditions is essential to ensure the cable’s expected life span will not be affected. The use of wire and cable products outside their designed temperature range can result in premature and often expensive failures in service.

High-temperature wire is often defined as a wire with a temperature rating of 125°C or higher, although high-temperature can also refer to temperature ratings as low as 90°C. High-temperature cables can either be single-conductor or multiconductor. These products commonly consist of a conductor (usually annealed, tinned copper, copper-plated or nickel-coated copper) and insulation. High-temperature wires may also have an additional jacket consisting of a fiberglass braid or K-fiber material.

Two key components to ensure high-temperature wires are suitable for the application are the wire’s temperature rating and ampacity. Temperature ratings can be defined as the maximum continuous temperature that a wire can withstand during its lifetime. If a cable’s temperature rating is not suitable for the environment and ambient temperature, the expected lifespan of the cable could be affected.

The ampacity is the maximum current an insulated conductor can safely carry without exceeding its insulation and jacket temperature limitations. If the cable is undersized, the heat produced by circuit load may exceed the cable’s temperature rating and the cable may be compromised.

Detailed Parameters

Fiberglass:

Fiberglass (US) or fibreglass (UK) is a common type of fiberglass-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet (called a chopped strand mat), or woven into a fabric. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinylester—or a thermoplastic.

Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, and can be molded into complex shapes. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, casts, surfboards, and external door skins.

Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK (from German: Glasfaserverstärkter Kunststoff). Because glass fiber itself is sometimes referred to as "fiberglass", the composite is also called "fiberglass reinforced plastic". This article will adopt the convention that "fiberglass" refers to the complete glass fiber reinforced composite material, rather than only to the glass fiber within it.

The process of manufacturing fiberglass is called pultrusion. The manufacturing process for glass fibers suitable for reinforcement uses large furnaces to gradually melt the silica sand, limestone, kaolin clay, fluorspar, colemanite, dolomite and other mineralsuntil a liquid forms. It is then extruded through bushings, which are bundles of very small orifices (typically 5–25 micrometres in diameter for E-Glass, 9 micrometres for S-Glass)
