Cross section of guide frame made from glass fiber reinforced plastic is in ' 'shape. Cover with cross section in ' 'shape is added on the guide frame. A glass fiber reinforced plastic guide frame for cabling for a ship and a mounting frame thereof are provided. The cross section of the glass fiber reinforced plastic guide frame is a ''U'' shape, and a cover with the cross section of ''n'' shape is added thereon. The frames of the glass fiber reinforced plastic guide frame are an ''E'' type combination frame, a ''Y'' type combination frame, an ''L'' type frame, a ''U'' type bracket, a reverse "<" type bracket or a linear frame. The type of the mounting frame is selected according to the structure of the ship body and the type of the glass fiber reinforced plastic guide frame and the mounting frame is welded on the corresponding position after selection. A cable is arranged in a ''U'' type groove of the glass fiber reinforced plastic guide frame supported on the mounting frame. The glass fiber reinforced plastic guide frame and the mounting frame of the invention play support and protection role for the cable in the ship, have advantages of insulation and anti abrasion or the like, and can save the welding time of the construction on site, improve the construction efficiency, and greatly improve the stability of the welding.
