Answer:

(1) The bracket should be complete and the paint should be complete.

(2) Cable type, voltage and specifications are in accordance with the design.

(3) The cable insulation is good. When there is doubt about the sealing of the oil-paper cable, it should be judged by damp; the direct-buried cable and the small-bottom cable should pass the DC withstand voltage test; the oil sample of the oil-filled cable should pass the test.

(4) The oil pressure of the oil-filled cable should not be lower than 1.47 MPa.
