In order to consider insulation requirements, in the production of AC distribution cabinets, DC distribution cabinets, UPS cabinets, UPS two-class distribution cabinets, DC two-level distribution cabinets, battery cabinets and other racks on the copper platoon mostly need a set of mother exhaust heat shrinkage pipe, today we to learn the copper row of the mother drain heat shrinkage pipe process.

Ready to work

Prepare the copper row of the heat shrinkable tube and clear the connection between the copper rows.

Prepare the corresponding specifications and colors of the mother drain heat shrinkable tube, scissors, hair dryer.

Technical Requirements

According to the Copper row width, select the appropriate heat shrinkable tube to ensure that the heat shrinkable tube after hot shrinkage leveling, close, no distortion, deformation, warping and other phenomena.

The heat shrinkable tube after heat shrinkage should be free of breakage, and the word on the heat shrinkable tube should form a straight line.

Process

Tools: scissors, hair dryer, telescopic blades, steel ruler

Material: Mother Drain heat shrinkable tube

Prepare the corresponding copper chops according to the assembly drawings and select the appropriate parent drain heat shrinkage tubes.

Thermal shrinkage tube with corresponding length of copper row shear

The shear incision should be perpendicular to the axis of the heat shrinkable tube when the shear heat shrinkage tube is cut.

The length of the mother drain Heat shrinkable tube is slightly longer than that of the copper row to be set, and the length of the copper row after the heat shrinkage is appropriate.

such as a copper row evenly distributed multiple holes, and the distance between the hole spacing ≤20mm the copper row is not a heat shrinkable tube.

The copper row of the heat shrinkable tube is neatly placed on the workbench with the appropriate temperature of the hot hairdryer (the heat shrinkable tube can be shrunk to 1/2~1/3 when heated to more than 100 degrees) from one end of the copper row to the other end of the copper row slowly and uniformly. Turn over the copper row and blow the other side of the heat shrinkable tube in the same way until the heat shrinkable tube is dressing onto the copper row.

Cutting, after blowing the heat shrinkable tube should be based on the copper row of the hole and the row to be joined to determine the cutting length, first will be blown after the number of holes and specific position on the copper row, can be pressed up and down the hand, and then according to the row to be joined to determine the cutting length, to join the center of the hole as the , be careful not to scratch the copper chops when cutting.

If the hole in the row is connected to the insulating column, the edge of the heat shrinkable pipe is 1/2L+5mm from the center of the insulating column (L is the width between the two parallel pairs of the insulating column).

If the row of the hole and shunt joint is based on the shunt and copper row connection width.

The mother drain heat shrinkable tube should be completely cut, can not have the bristles, not torn, hot shrinkage tube after cutting to be straight and beautiful.

When two copper rows are superimposed and connected at the same time, the two copper sleeves are lined with a heat shrinkable tube.

The above is the mother drain heat shrinkage tube Set bronze medal use specification.

配电柜用铜排套母排热缩管的工艺流程

为考虑绝缘要求，在生产交流配电柜、直流配电柜、UPS柜、UPS二级分配柜、直流二级分配柜、电池柜等机架上的铜排大都需要套母排热缩管，今天我们来学习下铜排套母排热缩管的工艺流程。

准备工作

准备好该套热缩管的铜排，清楚铜排之间的联接。

准备相应规格与颜色的母排热缩管、剪刀、电吹风。

技术要求

根据铜排宽度选择适当的热缩管保证热缩管热缩后平整、紧贴，无扭曲、变形、翘曲等现象。

热缩后的热缩管应无破损，热缩管上的字应形成一条直线。

工艺流程

工具：剪刀、吹风机、伸缩刀片、钢板尺

材料：母排热缩管

根据装配图准备相应的铜排及选择与之相适应的母排热缩管。

对照铜排剪相应长度的热缩管

剪热缩管时剪切口要垂直于热缩管轴线。

母排热缩管的长度要比待套铜排长度略长，以热缩后与铜排待覆盖长度相适应为准。

如一根铜排上均匀分布多个孔，且孔距之间距离≤20mm则这根铜排可不套热缩管。

套完热缩管的铜排整齐码放到工作台上用热吹风机合适的温度（热缩管在加热到100度以上时直径可缩到1/2～1/3）从铜排的一端缓慢匀速的吹到铜排的另一端。翻过铜排用同样的方法吹热缩管的另一面，直到热缩管敷贴到铜排上。

切割，吹后的热缩管应根据铜排上的孔和待联接排来确定切割长度，首先将吹后的铜排上的孔数和具体位置确定，可用手上下左右按下，然后根据待联接排来确定切割长度，以联接孔的中心为基准两端各切掉1/2L+5mm(L为待联接排的宽度)，切割时注意不要划伤铜排。

如排上的孔是和绝缘柱联接，热缩管边要距绝缘柱中心为1/2L+5mm (L为绝缘柱两平行对边间的宽度)。

如排上的孔和分流器联接则以分流器与铜排联接宽度为准。

母排热缩管要完整切割，不能有毛边，不可撕裂；热缩管切割后要平直美观。

当两根铜排叠加使用同时联接时，这两根铜排套一根热缩管。

以上即为母排热缩管套铜牌的使用规范。
