Chapter 2 Technology Contents
1. 电缆敷设的准备工作Preparation for cable installation
1.1准备“电气综合放样图（即电装图）”“电气设备布置图”“电气焊装图”“电
缆清册”等有关电缆敷设的施工用图纸及技术文件。
Prepare the electric integrate drawing, electrical equipment arrangement drawing, cable-supporting installation drawing, cable list and other drawings and technical documents for cable installation.
1.2根据主干电缆表册，进行电缆切割备料。
According to the cable list, pre-cut the cables and store.
1.3发电机到配电板，首侧推电机的电源线及到起动电阻箱或变压器的电缆，这些线径大，长度相对较短，不预裁备料，采用现场敷设的办法。其它一次电缆要根据表册，按所划分的区域进行切割备料。事先应做好电缆的临时标牌，标牌上注明电缆代号、规格，每根电缆首尾各一块。每根电缆切割时，随即将临时标牌包扎于该电缆的起、终两端，按照电缆表册规定的长度，做好电缆穿过舱壁或甲板的停止标记。 预裁备料时，注意先裁后敷的原则，既可保证敷设美观，又做到了尽量避免敷设时交叉的现象。
The cables from generator to switchboard, the power supply cable for bow thruster motor and from the motor to resistor or transformer, the diameters are bigger and lengths are shorter, so it is not necessary to pre-cut. The cables should be cut on board. Other cables will be pre-cut and wrapped on the cable windlass, then marks zone number and labels on the two ends of the cables according to the cable list. Give clear information of the cable name and spec. According to the stop length shown on the cable list, mark stop sign on the cable. To be care that the cable cut first should be laid out last.
1.4电缆的切口应保证不因受潮而影响绝缘，必要时应妥为包扎封口。
The cable cut should not been effected by damp lead to influence the insulation performance. If necessary, please pack the cable ends.
1.5按照表册规定的拉敷地点及拉敷顺序，分区将电缆依次卷入电缆盘备用。注意须将电缆表册中各区域内排在前面的大截面电缆最后预裁，可以优先敷设，从而尽量减小电缆相互磨擦而损伤电缆护套的可能性。
Wrap the cables on windlass according to the information showing on the cable list. Pay attention to the bigger diameter cables in the front of each zones should be pre-cut at last, which can been laid out at first to avoid the cables grind each other lead to damaged the cable sheath.
1.6按照施工图纸将预先配制的托架，电缆框、电缆筒、填料函等进行实船定位，划出其开孔位置及尺寸。
Install the penetrations, glands and cable tray base on the construction drawing on board.

1.7在船体构件上开孔Hatch on hull structure
开孔一般为圆形或腰圆形，如开孔为其它形状则至少应有圆角，安装电缆框、电缆筒或电缆管时，孔的大小应与所选定的电缆框、电缆筒或电缆管相称，不宜过大。 The hole should be rotundity or rectangle with round corner, install penetration or cable pipe, the dimension of hole to be suit to the transit, not too big.
1.7.1在横梁、肋骨及纵桁上开孔 见下图1。 Hatch on beam、rib or vertical joist, see follows figure 1,
图1 Figure 1
1—甲板deck 2—肋骨frame 3—孔hole 4—纵桁vertical joist
5—纵桁面板faceplate 6—切口边缘cut edge
a. 开孔高度b一般不得超过横梁肋骨或纵桁高度B的四分之一（25%），宽度l不得超过骨材间距L的五分之三（60%），开孔的左右边缘尽量做到与切口边缘等距离。
The height of hole b, should not exceed than one quarter (25%) of B, the height of the beam, rib or vertical joist. The width, l, should not exceed than three-fifths (60%) of the distance L between the two frames. If possible, the two distances to be equality, which from the hole left and right edges to the cut edges.
b. 开孔位置应靠近甲板，即开孔下缘至纵桁面板的距离h应不小于纵桁腹板高度B的五分之二（40%）
Position of the hole should be closed to the deck. The distance from low edge of hole to the faceplate should not less than two-fifths (40%) of B, the height of the vertical joist.
c. 开孔应分散，不能同时密集在邻近的纵骨间距或肋距之内，如需开二个或二个以上的开孔时，应沿水平方向布置，但所有孔的宽度之和不得超过纵骨间距或肋骨间距的二分之一。如开孔不符合上述规定，应予以强度补偿。
The holes should be arranged separately, those should not be centralized between the two frames. If cut two or more holes, those should be arranged on level line, and the sum of the widths of the holes should less than half of the distance between the two frames. Otherwise, the reinforcement should be considered.
