This standard is equivalent to IS05828:2001 "Dimensions and characteristics of secondary connection cables connected to water-cooled connections at both ends of resistance welding equipment" (English version).
Compared with JB/T10113—1999, the main changes of this standard are as follows: 1. The type of cable is increased, that is, the high-flexible cable is added (Chapter 3 of the 1999 edition; Chapter 2 of this edition). Detailed provisions are made for the chemical composition and conductivity of the materials used for the secondary connecting cables (Chapter 6 of the 1999 edition: Chapter 5 of this edition!
This standard replaces JB/T10113-1999.
This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Standardization of Electric Welding Machines. This standard is drafted by Chengdu Electric Welding Machine Factory. The main drafter of this standard is Zhang Longzu.
This standard was first issued in March 1989, revised for the first time in April 1999, and changed from a national standard to an industry standard. 1
1 Scope
Dimensions and characteristics of secondary connecting cables connected to water-cooled connection blocks at both ends of resistance welding equipment
JB/T10113--2002
This standard specifies secondary connecting cables that are air-cooled in their length and connected to water-cooled connection blocks at both ends. Size and characteristics of the connecting cable. The secondary connecting cable is used for the connection between the secondary terminal of the welding transformer and the electrode connector. 2 Classification
The secondary connecting cable is divided into three types according to the diameter of the copper wire: low softness (LF), softness (F) and high softness (HF) (see Chapter 6)"
3 Size
The size of the secondary connecting cable is shown in Figure 1 and Table 1. Table 1 Size
Note: The values ​​in brackets should be avoided as much as possible. 315
Allowable continuous current
, the listed values ​​are based on the R20 priority number system, and the values ​​in between can also be selected according to the R40 priority number system. . At a given negative cut-off duration, the allowable secondary current x can be calculated as follows: f100
The values ​​listed in the table are based on the temperature rise of 60°C and the water-cooling connection blocks at both ends of the cable. 500

The marking of the secondary connecting cable consists of \secondary connecting cable, "code of this standard\, "cable cross-sectional area (mm2)", \length (mm) and "flexible type" as desired.
Example: The marking method of the flexible type (F) secondary connecting cable with a cross-sectional area of ​​400mm and a length of 500mm is: Secondary connecting cable JB/T10113—400×500—F5Material

Maximum mass resistivity: 0.153282·g/m (at 20c) Note: Equivalent value for reference:
Maximum volume resistivity: 0.017241 (2mm2)rm Minimum conductivity: [00%IACS or 58ml【mm】2 The external insulation layer used to protect the secondary connecting cable should be resistant to general industrial chemical reagents and possible splashing, and be able to withstand a maximum temperature of 100°C without damage.

The minimum twisting limit of the cable along the length is half a turn. 7 Durability test (type test)
7.1 Test conditions
For single-sided double spot welding, according to the test device and dimensions of Figure 2, one end of the secondary connection cable is connected to the water-cooled secondary terminal of the transformer: the other end is connected to the water-cooled electrode connector, and the middle part of the secondary connection cable does not need to be supported. Under the condition of a load duration of 4%, run uninterruptedly at a rate of 20 times per minute for at least 8 hours. 2

The applied welding current shall be calculated according to the value given in Table 1. Under these conditions, the secondary connecting cable shall be able to withstand 300,000 kV mechanical and electrical operation tests.
7.2 Determination of test results
At the beginning and end of the durability test, the resistance value of the secondary connecting cable shall be accurately measured at 20°C. The difference between the maximum resistance value and the initial value shall not exceed 15% of the initial value. 8 Marking
Secondary connecting cables that meet the requirements of this standard shall be marked with the cable cross-sectional area, length and the letters LF, F or HF at the terminal ends on both sides as required in Figure 1.
