Question
DIFFERENCE BETWEEN POWER AND CONTROL CABLES
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Power cable mainly intend to use transfer of power,
specifically current, over a defenite length.
According to the rating there will be change in the no. of
starnds etc for a.c.

control cables are mostly paired cables ,sometimes more
flexible than power cable. and are not intend to carry more
than 10A.(max.).

Answer
# 2
there are voltage levels in power transfer.. two types of
voltage is there, one is control voltage and power voltage.
control voltage starts from (0-230), power voltage from
0 - 433kv.. so depending upon the application we are
distinguishing.. even the same 230 v can be used as control
as well as power voltage also....

Control cable are very much flexible than power cables.
power cables have high tensile strength than control cables.
power cables used for high power transfer from one side to other
control cables use 230v maximum

the power which is gernated in a station has high potential
and are transmitted by power cable like aac acsr etc which
have large diameter or high no.of strands. while control
cables are used in stations to control various activities of
equipments in stations like colling fan scontrols panel etc
in hydro plants also they are more flexible

A POWER CABLE CAN BE OF MAXIMUM 4 CORE ONLY BUT OF ANY SIZE
DEPENDING UPON THE CURRENT CARRYING REQUIREMENT.
A CONTROL CABLE CAN BE OF ANY NO. OF CORES BUT USUALLY TO
CARRY CURRENT UPT0 10AMPS

Answer
# 6
for the control of any circui few amperes of current is
required so normally we use a small cross-sectional wires.
This current can be mA to Few Ampers and risk of FAULT
current flowing is less and normally a single phase so we
require a small cable of 2 core or 3 core or less cross-
section.

The power cables is used depending on the application in
the Amperes to KA and the FAULT current is more and in the
range of KA.So the application of this cable is to supply a
several Ampere of current and Voltage ranging from the 230
V to Several KV depending on the load.So this cable is
called power cable as it is used to feed power.

Even based upon the application the cables are called as
Power and Control Cables.

Answer
# 7
1. Power Cables having more size than control cables
2. power cables used for direct High voltage power.
3.Control cables used for wiring in control panels,
controling divices.
4.Power cables having more dia. than control cables.
5 Power cables requires cable terminal kit & control cables
didnt requires of it.

According to cable types and size
1Cx2.5sq.mm to 4CxMax. Sq mm - Power cables

3Cx1.5sq.mm to 27Cx2.5sq.mm-Control Cables

Control Cables are available in 1.5sq.mm and 2.5sq.mm-Only
in Cu.
Power Cables are available from 1Core to 4Core and 2.5sq.mm
to 630sq.mm in Al. and Cu

Power cable is connecting the Power circuit. whereas control
cables is connecting the control circuit.
