The main points of cold shrink tube installation are as follows:

1. Confirm that the model and specifications of the cold-shrinkable tube should match the cables to be installed; confirm that the accessories of the cold-shrinkable tube are complete and prepare the tools required for installation; read the installation instruction drawings; ensure that the installation environment meets the requirements of moisture-proof and dust-proof, It is not suitable for construction when it rains and when the dust is too large.

2. Technical points for cable pre-treatment: check whether the cable to be installed is wet or infiltrated; clean and straighten the installed part of the cable; if there are scratches on the outer surface of the cable, especially near the shield opening 20mm, use abrasive cloth to smooth it. To prevent residual air gaps; do not allow the insulation parts to be cleaned with detergents that have been used to clean metal parts; the metal parts of the cable should be flat and smooth without oxidation, and there should be no burrs, nicks, or flanging. Clean the file or abrasive cloth after processing.

3. Basic operation of cold shrink sleeve installation: After the installation is completed, it is impossible to know whether the position is accurate from the outside. Therefore, it is necessary to strictly follow the steps specified in the installation instructions of the cold shrink sleeve. Displacement during installation; If there is waterproof tape or foam strip, avoid exposing the waterproof tape or foam strip too much; do not bind hard materials such as wire or cable tie outside the installed cold shrink tube to avoid scratching.

冷缩管的安装要点

冷缩管安装要点，主要有以下几个方面：

1、确认冷缩管型号规格应与要安装的电缆相匹配；确认冷缩管的附件齐全，准备好安装所需的工具；读懂安装说明图纸；保证安装环境符合防潮、防尘的要求，下雨时以及扬尘太大时不宜施工。

2、电缆预处理的技术要点：检查待安装电缆是否受潮进水；清洁并校直电缆的被安装部分；电缆外表面如有划伤痕迹，尤其靠近屏蔽口20mm范围，要用砂布打磨光滑，以防残留气隙；不允许用清洁过金属部分的清洁剂再清洁绝缘部分；电缆金属部分应平整、圆滑，无氧化现象，不能有毛刺、缺口、翻边等，如发现有以上情况，可用锉刀或砂布处理后并清洁。

3、冷缩套管安装的基本操作：由于安装完毕后，从外面无法了解位置是否准确，因此要严格按照冷缩套管安装说明规定的步骤进行；注意需要做好安装时的固定工作，防止安装时发生位移； 如有防水胶带或泡棉条，需避免过多暴露防水胶带或泡棉条；不得在安装完毕的冷缩管外面再绑扎铁丝或扎带等硬质材料，避免划伤。
