The cable with Category A rated voltage is used in the situation
requiring not over 1 min. of grounding fault lasting time. For the
cable with Category B rated voltage, the grounding fault lasting
time normally is not over 1 hour, max. lasting time is not over 8
hours, annual ground fault lasting time altogether should not be
over 125 hours, Category C includes all the system expect Category
A and B.
Applications
These power armoured cables are designed for open air installation,
for direct burrial underground, in water, in cable ducts, power
stations, where mechanical damages to the cable may occur.

We are capable of meeting the most strict delivery schedules
according to per purchase order. Meeting the deadline is always the
top priority as any delay in the delivery of cable can contribute
to overall project delay and cost overrun.
Cable is supplied in wooden reels, corrugated boxes and coils.
Cable ends are sealed with BOPP self adhesive tape and
non-hygroscopic sealing caps to protect the cable ends from
moisture. The required marking shall be printed with a
weather-proof material on the outsides of drum according to
customer's requirement.
