Phthalocyan Bluenato cyan blue pigment is used.

場合、過電流が流れて絶縁体が損傷に受けるとし１う問
題があった。Cross-linked polyethylene insulated wires using Tokoroka and cyan blue pigments have a problem in that if a short circuit or the like occurs during use, an overcurrent will flow and the insulator will be damaged.
この原因は、架橋ポリエチレンにシアンブルー系顔料を
含有させると、常温（例えば２０°Ｃ）では機械的（！
ｌ’Ｗに引張り）強度が充分であるものの高温（例えば
２００°Ｃ）にさらされると強度が著しく低下するため
と跨えられ、従って短絡事故等が起きた場合に過電流に
より導体近１カの絶縁体は２００°Ｃ近くまで昇温する
可能性があり、その為、損傷を受けるものと思われる。The reason for this is that when cross-linked polyethylene contains a cyan blue pigment, it becomes mechanical (!
Although the strength is sufficient (tensile to l'W), the strength decreases significantly when exposed to high temperatures (e.g. 200°C). Insulators can be heated to temperatures close to 200°C and are therefore likely to be damaged.

As a method of increasing the amount of crosslinking agent, there is a method of increasing the amount of crosslinking agent once or completely, but this method has the problem that scorch is likely to occur during extrusion. There is also a method of adding all the filler for reinforcement, but this method causes a 1-increase in torque during extrusion processing, significantly lowers the processability, and is not necessarily desirable. isn't it.

こともない。Since the crosslinked polyethylene insulator according to the present invention is colored with the above-mentioned inorganic blue pigment, there is no significant decrease in mechanical strength at high temperatures compared to an insulator colored with cyan blue pigment. Increase the amount of crosslinking agent,
DnT properties are not impaired by adding all the filler.
