These ribbons are divided into two categories, high temperature tapes (PET) and low temperature tapes (PE). The former is used for color distinguishing of power cable and warm water cross-linking polyethylene insulated cable, and the latter for telecommunication cable and high voltage cross-linking polyethylene insulated cable.
Quality requirement (1) The tapes shall be smooth and without fold, twist, hole, crack as well as foreign matter. (2) On the parallel double color tapes, the width of each color shall be not less than 1.5mm. The color shall be clear and uniform. (3) The edges shall be not folded. The shape of core shall be two semicircles or have not horizontal cut for convenient to take out from core.
