All typical values were tested by press moulding sample under the condition of 180±2 ℃,15min, and pressure over 15Mpa, then cooling to room temperature
Referring to the JB/T10437-2004 standard, the company standard specified that in every 1kg sample of grade 4205TR-35, the impurities with diameter 0.175 ~ 0.250mm must not be more than 5 pieces, the impurities with diameter more than 0.250mm must be zero.
We have strict control over theraw material of product grade 4205TR-35, which has been produced under purified environment. The typical value of product impurity content is:
Particle diameter (mm) No. of particle
0.175-0.25 1
>0.25 0

- Q:What is the warranty period for wire and cable?
- Wire and cable warranty period is 30 years of national warranty period. But the specific warranty period according to the type of wire and cable and the use of conditions and temperature and applicable methods to determine. General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use.
