Filled cable is a type of cable construction in which the cable core is filled with a gel material. This gel material is designed to prevent moisture from entering the cable or passing through it. Filled cable is used in many applications as a way to protect against moisture damage and corrosion.
When assembling a filled cable, the core of the cable is first filled with gel material. This material is typically a liquid that has been formulated to be highly resistant to moisture. The liquid is poured into the cable core until it is completely filled. The gel material is then allowed to harden and form an impermeable barrier that prevents moisture from entering the cable.
The gel material used in filled cables also has the benefit of providing insulation and protection against electrical shock. This is especially important in applications where the cable is exposed to wet conditions. By preventing moisture from entering the cable, the insulation properties of the cable are better maintained.
The outer jacket of a filled cable is usually made of a durable material such as rubber, PVC, or nylon. This outer jacket helps to protect the gel material from being damaged or disturbed. Additionally, the outer jacket helps to protect the cable from damage due to abrasion or other external factors.
Filled cable is commonly used in a variety of applications, ranging from underground wiring to telecommunications. This type of cable construction is especially useful in areas that are prone to high levels of moisture or humidity, as the gel material helps to prevent moisture from entering and damaging the cable.
