INSULATING TAPE FOR COATING CONNECTION PORTION OF POWER CABLE, METHOD FOR FORMING INSULATING COATING ON EXTERIOR SURFACE OF CONNECTION PORTION OF POWER CABLE, AND POWER CABLE
20220157486 · 2022-05-19 · ·

An insulating tape for coating a connection portion of a power cable is unlikely to cause local cracking to a fused part even when a highly hydrophilic polyethylene is used. This insulating tape is formed of a resin material including a polyethylene which is at least partially modified by a molecule capable of imparting hydrophilicity; an antioxidant; and a cross-linking agent. The antioxidant has a molecular weight of not less than 190 but less than 1,050. The contained amount of the antioxidant is 0.05-0.8 parts by mass with respect to 100 parts by mass of the polyethylene. The insulating tape has a thickness of 50-250 μm. In addition, this power cable 1 is provided with a connection structure that has a connection portion formed by conductively connecting ends of multiple power cables where respective conductors are exposed. An insulating coating is formed on the exterior surface of the connection portion by at least winding and cross linking the aforementioned insulating tape around the circumference of the connection portion.

WELD POSITIONING CLIP FOR ENCAPSULATION PROCESS

A cable clip for engaging around an exposed conducting core of a cable during an encapsulation process. The clip is formed as a rectilinear loop having an inner surface and an outer surface and opposed ends which define an opening in the loop therebetween by means of which the clip can be engaged around the exposed core. The clip has posts distributed around, and extending outwardly from, its outer surface. The posts engage with an inner surface in an encapsulation mold enclosed around the clip so as to maintain a minimum spacing between the mold and the outer surface of the body around the entire clip and thereby ensure a minimum thickness of encapsulation sealant is formed around the exposed core of the cable during the encapsulation process.
