CATV Drop Cable



NEPTCO is the world's major supplier of CATV shielding tapes for dual, tri and quad shield cable designs. Our fusible tape, which is designed to form a destructible bond to both polyethylene and aluminum, allows for ease in termination and aids in meeting water path penetration specifications. Our high strength tri and quad shield outer tapes allow for ease in processing and ensure shielding integrity. Tri-shield tapes designed to bond to PVC jackets are also available.

Construction:

Foil/film/foil shielding tapes are constructed of one layer of polyester, polyethylene, or polypropylene film laminated between two layers of aluminum or copper foil.

Features/Benefits:
  • Foil-to-foil contact at overlap
  • Enhanced shielding
  • Improved durability

Selecting the product that's right for you:

Films
  • HIGH-DRAW foil/film/foil laminates offer exceptional draw characteristics and resilient shielding.
  • Polyester films have a higher temperature resistance than polypropylene and therefore are often selected for use directly under an extruded jacket.
  • Polypropylene film laminates are more flexible and economical due to their high yield.
  • Polyethylene film is both economical and offers resistance to chemicals.
  • Thicker film substrates provide higher dielectric and tensile strengths.

Foils
  • Aluminum is lighter in weight and more cost effective than copper
  • Copper offers resistance to corrosion and radiation; soldering at termination; and higher conductivity relative to aluminum
  • Thicker foil substrates provide higher conductivity and tensile strength, and lower signal attenuation.
