5.4.3.2 Making of cable end and the connector
The making of cable end and the connector must be conducted by experienced personnel
and follow working rules.
When making cable end and connector with the voltage higher than 6Kv outside, the
Relative Humidity (RH %) must be around 70%. When relative humidity is high, heathen
ambient temperature or cable.
When making plastic insulation cable end and connector, avoid the dust falling into the
insulation and do not process during the fog or raining days.
Please follow the requirements below:
1.
Type and specification must follow the cable type e.g. voltage, core numbers,
protection layers, and environment.
2.
The structure must be easy, compact for installation.
3.
Materials and parts must meet the technical requirement.
4.
Performance must follow current national standard.
The insulation materials should be not only aligned with demands, but also compatible with
cable insulation. Hardness, expansion coefficient, tensile strength, and breaking extension
of these two materials must be similar. Rubber insulation cable must apply high viscosity
and elasticity materials as additional insulation.
When connecting core and amour clamp, must apply standard connecting tube and wiring,
the inner diameter must be compatible with core and the intersecting surface must be
1.2~1.5 bigger than the intersecting surface of core. When press bond, coaxial cable press
pliers and mold must meet the specification requirement.
Working Inspection
：
Before making the end of cable and connector, must be familiar with working information
for installation, ensure the inspection procedure, and meet the demands below:
1. Ensure the insulation of cable is in good condition without damping, and no moisture is
allowed inside the plastic cable. Test the electronic performance which must be aligned
with the standard.
2. The specification of accessories must be the same with cable, no injury parts, no
damping of insulation materials, and sealing materials must work. Assemble
