1. Product Introduction
The flame retardant water blocking filling rope is a kind of water blocking material used in cables which is made of polyester fiber non-woven fabric and super absorbent resin through impregnation, bonding, drying, and finally twisting.This rope has characteristics with water resistance, heat resistance and chemical stability, no acid and alkali, no corrosion,large water absorption capacity, high tensile strength, low moisture content, etc. Normally, outdoor cables are laid in a damp and dark environment. If damaged, the water will flow into the cable along the damage point and affect the cable by changing the capacitance of the cable and reduce the signal transmission strength. The XLPE insulated power cables will generate water branches, which will seriously cause insulation breakdown. Therefore, in order to prevent water from entering into the cable, some waterproof materials will be filled or wrapped inside the cable. The water-blocking filling rope is one of the most commonly used water-blocking filling materials because of its strong water-absorbing capacity. At the same time, the water-blocking filling rope can make the cable core round and improve the cable appearance quality and increase the cable tensile performance. It can not only block the water, but also fill the cable. The water-blocking filling rope we provide has the following characteristics: 1) Soft texture, free bending, light bending, no delamination powder; 2) Uniform twist and stable outer diameter; 3) The gel is uniform and stable after expansion; 4) Unloose winding.
It is suitable for filling water resistance type power cables, marine cables, etc.
