摘要： PURPOSE:To easily estimate the crosslinking temp. of low-density polyethylene (LDPE) in a short period of time by measuring the gel fraction of the LDPE contg. an antioxidant heated and crosslinked by using a dicumyl peroxide. CONSTITUTION:The gel fraction of the LDPE contg. the anitoxidant heated and crosslinked by using the dicumyl peroxide is measured. The temp. at the time of the heating and crosslinking is measured from the measured data and the relative data on the previously established crosslinking temp.-gel fraction. The crosslinking temp. of the LDPE of power cables under mass production or a large quantity of the power cables currently under working is thus easily estimated in a short period of time.

摘要： PROBLEM TO BE SOLVED: To enable to manufacture repeatedly and stably cables of not only straight shape but also complicated curvature shape with fewer work processes than before without requiring a carrier sheet. SOLUTION: A first adhesive layer 2 made of hot-melt adhesive and a pressure sensitive adhesive layer 3 that adheres to the conductor foil at the temperature at which the first adhesive layer does not melt, and does not adhere in substance to the conductor foil by increasing the temperature with reduced adhesion, are laminated in this order on one face of a first insulating resin sheet 1. On the pressure sensitive adhesive layer 3, a conductor foil 4 is adhered at the temperature at which the first adhesive layer 2 does not melt, and a plurality of lead wires 4a are punched out, and then, by increasing the temperature, the adhesion of the pressure sensitive adhesive layer is decreased and the remaining material of the conductor foil is removed. Then a second insulating resin sheet 6 having a second adhesive layer 5 made of hot-melt adhesive formed on one face is overlapped, and after heating and pressuring, the first and second insulating resin sheets 1, 6 are adhered clipping plural lead wires and a laminated structure 8 is formed.
