Condition causes the effect of partition, grid etc. to be failed, and in actual production process, the components such as setting partition, grid in MPP is managed
And it is extremely cumbersome and inconvenient, improve production cost.(3) existing MPP pipe is general cylindrical, the outer surface of MPP pipe compared with
Be it is smooth, cause MPP pipe be embedded to underground after, stability is lower, it may occur that offset, rotation situations such as so that the cable in pipe is same
Situations such as step shifts, rotates, to destroy cable.
