Scope
This part of GB/T 7113 specifies requirements for three types of braided or knitted E-type glass fiber sleeving with a continuous acrylic based coating, differentiated by breakdown voltage (GB/T 7113.4-403 type: high breakdown voltage; GB/T 7113.4-404 type: medium breakdown voltage; GB/T 7113.4-405 type: low breakdown voltage). Practice has proven that this sleeving is suitable for use at 155°C and below. The nominal internal diameter of this type of sleeving is typically between 0.30 mm and 25.00 mm, with wall thickness between 0.15 mm and 1.20 mm, and is available in the following colors: black, white, red, yellow, blue, brown, green, green/yellow, and natural. In addition to the dimensions or colors listed in this part, other dimensions or colors can be customized according to customer requirements. These products, if they meet the requirements listed in Tables 2 and 4 for properties other than dimensions, shall be considered as conforming to this part. Materials that meet the requirements of this part have achieved established performance levels. However, when selecting materials for a specific application, users should choose based on the actual requirements necessary for that application, and not solely on this part.
GB/T 7113的本部分规定了三种具有丙烯酸酯连续涂层且以击穿电压的不同来区分的(GB/T 7113.4-403型：高击穿电压；GB/T 7113.4-404型：中等击穿电压；GB/T 7113.4-405型：低击穿电压)编织或针织E型玻璃纤维软管的要求。实践证明，该软管适合于155℃及以下使用。该类软管的内径通常在0.30mm至25.00mm之间，其壁厚在0.15mm至1.20mm之间，并具有下列颜色：黑色、白色、红色、黄色、蓝色、棕色、绿色、绿/黄色及本色。除了本部分所列出的尺寸或颜色，其他的尺寸或颜色可根据客户的需求定制。这些产品，如果除尺寸之外其他性能都符合表2、表4所列出的要求，则应视为符合本部分。凡符合本部分要求的材料，均已达到既定的性能水平。然而，用户在针对某一特定用途选择材料时，宜依据该应用所必需的实际要求来选择，而不应仅仅依据本部分。

Electrical equipment manufacturers and insulation material suppliers use this standard to regulate the production and testing of acrylic-coated glass fiber sleeving. By defining three breakdown voltage levels (high, medium, low) and strict requirements for dimensions, heat resistance, and flexibility, it ensures reliability and safety in electrical insulation applications up to 155°C. This standard is critical for maintaining consistent quality of insulating components in motors, transformers, and similar devices.
