Definitions
- the present invention relates to a crosslinked polyethylene cable having excellent characteristics against voltage deterioration, especially voltage deterioration at high temperatures.
- the present invention is intended to provide a cross-linked polyethylene cable having excellent characteristics against deterioration due to electric charge under high temperature.
- the gist of the present invention is that polyethylene has a VA content of 25%. Of less than 35% and less than 35% of ethylene vinyl acrylate copolymer with more than 10% and less than 30% and an organic peroxide compounded on the outside of the conductor by extrusion coating. It is a cross-linked polyethylene cable that is specially characterized by being cross-linked.
- the ethylene acetate vinyl copolymer used preferably has an amount of VA (weight% of vinyl acetate contained in the copolymer: 28-53%).
- the drawing shows a cross-sectional view of a cross-linked polyethylene cable.
- BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to practical examples and comparative examples.
- Table 1 As an abalone body, a 150 2 cross-linked polyethylene cable for 60 KV was prepared.
- the figure shows a cross section of these cables. In the figure, (1) is a conductor, (2) is an abrupt body, inside these cables) and outside
- the material used for the semiconductive layer (4) is NUC 0580 (manufactured by Nippon Maker Co., Ltd., trade name).
- the completed cable was energized so that the conductor could reach 90 ° C, and a voltage of 1 ⁇ 0 Y was applied.
- the breaking time The time from the start of charging until the cable breaks down (hereinafter referred to as the breaking time) is calculated, and the respective efficiencies are calculated based on the breaking time of Comparative Example 1 (3 34 hours).
- the characteristics of the cable for the deterioration of the applied voltage were evaluated. The results are shown in Table 1.
- the amount of V A is 25. It is clear from the results of Example 1 that the characteristics with respect to the deterioration of the electric charge are remarkably improved in the case of EVA exceeding the above range. Especially, in the case of EVA30% (actual example 2), it shows extremely excellent characteristics. Similarly, when the V A amount is 53%, excellent characteristics are exhibited. ⁇
- V A » ⁇ 0 E V A is further specified by the blending amount with polyethylene.
- EVA content was 40% or more as in the case of the cable of Comparative Example 5, it was slightly superior to that of Comparative Example 1. Power that is not necessarily satisfactory.
- Comparative Example 7 can be said for Comparative Example 7 by comparing with Example 1. On the contrary, even if the same E VA as that of the cable of Example 3 is used, if it is 10% or less, it should not be added as shown in Comparative Example 6.
- the crosslinked polyethylene cable according to the present invention is useful for high-voltage power transmission and for low-voltage wiring in factories and households. Shows excellent characteristics against deterioration and is good
