Then began to suppress, the experimental value is 1.5 times the working pressure, 30 minutes impermeable, pressure drop does not exceed 0. 05MP is qualified
2. Strong power acceptance: Use 500V insulation resistance meter to test the insulation resistance value of each circuit, and at the same time, it can test the quality of the used wires. Wires that do not meet the standard may be broken down;
3. The weak current adopts the special tool test: The special network test tool tests whether the 8-core signal of the network is unimpeded; the carrier's copper shaft cable test tool, the multimeter and other complete tests are qualified before the next construction work.
