Four-core triangular cable with reinforcing ribs

The invention provides a four-core triangular cable with reinforcing ribs. The cable is of a rectangular structure and comprises a rectangular outer protective sleeve and four triangular cable cores which are stranded in the outer protective sleeve to form a triangular shape, wherein the reinforcing ribs are filled between the cable cores and the outer protective sleeve; each cable core comprisesa triangular insulating layer and one to three wire cores arranged in the insulating layer. The reinforcing ribs are arranged on contact surfaces of the four triangular cable cores. According to the four-core triangular cable provided by the invention, the wire cores and the cable cores are straightly dragged, so that filling materials and wrapping tapes are saved, wastes of materials for stranding to increase the length are reduced and the weight is reduced. 本发明提供了种带加强筋的四芯三角电缆，该电缆为矩形结构,包括矩形外护套以及外护套内绞合成三角形的四根三角形缆芯,缆芯和外护套之间通过加强筋填充；所述的缆芯包括三角形绝缘层以及绝缘层内的至三根线芯。所述的四根三角形缆芯接触面上设置有加强筋。本发明线芯和缆芯均直拖，节省了填充材料和包带，减少了绞合增加长度的材料浪费，减轻了重
