(d) Control cable cross section is generally not more than 10 square, power cable is mainly the power of that are generally large cross section. Power cable of the specifications of the generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section, can do manufacturers is relatively less, and control the cross section of the cable generally smaller, generally no more than 10 largest square.Some conclusions from the cable, power cable according to the request of power grid, most commonly for five core, and control cable transmission control signal, some more, according to the standard terms of more than 61 core, but also can produce according to user requirements.
