Explosion-proof cable for offshore oil platform This product is used to transmit automatic control signal for offshore oil platform with explosion risk and high explosion-proof requirements.
Ii. Conditions of use and product features:
Rated voltage: AC 250V;
② High operating temperature of conductor core: 70℃;
③ Low ambient temperature:
Fixed laying: -20℃;
Non-fixed laying: 0℃
The allowable bending radius of the cable shall not be less than 8 times of the cable diameter;
The cable has the characteristics of small distribution parameters, resistance to external interference and inter-line crosstalk.
Three, model:
1 a - CKWDZ.
Four, specification range:
① Two line group: 0.5~2.5mm2
② Three line group: 0.75~2.5mm2
③ Four-wire group: 0.75~2.5mm2
Logarithms of: 1, 2, 3, 4, 5, 6 (7), 8, 9, 10, 11, 12, 14, 16, 19, 24, 27, 30, 37, 44, 48, 50 (right).
Note: data can be provided separately if necessary.
Five, use matters needing attention:
(1) try to consider that it is not affected by or less by electrostatic induction and electromagnetic induction;
(2) Explosion-proof and non-explosion-proof lines are laid separately. There should not be a conduit or the same cable pipe, and it is not suitable to share the same cable box or the same line groove. If unavoidable, it must be isolated;
The wiring should not be damaged and protected;
(4) grounding of cable shield layer, single point grounding;
⑤ During storage, attention should be paid to the sealing of the finished cable head to prevent the cable head from dampness and reduce the insulation performance and affect the use.
