Protective grounding cable use
"Integrity service, abide by contract, and make friends" is the firm management philosophy of Zhengzhou company. We strictly and earnestly fulfilled the contract, honored our commitment, strengthened our after-sales service network system, and guided our service with newer and higher thoughts. Newer, higher products are dedicated to you. Let Zhengyuan's efforts be your satisfaction. All employees of Zhengyuan Company are looking forward to your visit to Shanghai.
First, the product features: JDX protective grounding wire consists of aluminum alloy die-casting clamps and high-quality copper wire, can be made according to the needs of the three-pronged, four-pronged, five-fork multiple forms, the personal security grounding process exquisite, structure Lightweight, suitable for personal security at the construction site.
Second, use: mainly used for low-voltage lines and electrical equipment above the line in the blackout maintenance of the secondary protection, to prevent the inspection of the line voltage induced damage, for security personnel to provide a reliable guarantee.
Third, the composition of the protective grounding wire :
The main components consist of security pliers, grounding tails across short-circuit lines, wiring noses (terminals), junction pipes, grounding clamps, grounding steel cables, and grounding operation bars. The grounding operating rods are made of glass fiber epoxy resin tubes with mechanical strength and excellent insulating properties according to the type requirements. The clamp is made of high quality hot copper (or mature aluminum) die-cast surface polished and wire-nose fastened. The wire is an important part of the portable short-circuit ground wire.

The composition of the personal security line: personal security clamp soft copper wire copper nose clamp
Personal security line configuration:
(1) Cross arm four-phase type: with 16 square grounded soft copper wire 4*1.5 meters +1.5 meters, with pliers or grounding rod
(2) Grounded four-phase type: with 16 square grounded soft copper wire 4*1.5 meters +1.5 meters, with pliers or grounding rod
(3) three-phase cross-type: with 16 square ground soft copper wire 3 * 1.5 meters +1.5 meters, with pliers or grounding rod
(4) Grounded three-phase type: with 16 square grounded soft copper wire 3*1.5 meters +1.5 meters, with pliers or grounding rod
Another can be customized according to actual needs of various lengths of personal security lines.
Fourth, the use and maintenance of protective grounding :
Before using the personal security cable, check the power before confirming that the power has been cut off and confirming that there is no voltage on the device. Connect the grounding clamp to the grounding net or flat iron first, and then use the grounding operating rod to tighten the wire end to the device wire. When removing a shorted ground wire, the sequence is exactly the opposite of the above. The short-circuit grounding wire installed, and the distance between it and the charged equipment, taking into account the influence of the ground pendulum, the safety distance should not be less than the value specified in the new "Regulations on power safety work". It is forbidden to use a winding method to short the ground without using a clamp. The portable short-circuit ground wire should be properly kept. Before each use, you should check carefully whether it is in good condition. The soft copper wire is not exposed and the nuts are not loose. Otherwise, they must not be used. The inspection period of the portable short-circuit grounding line is once every five years, and the inspection item is the same as the factory inspection. After passing the test, the qualified short-circuiting grounding wire should be judged according to the magnitude of the short-circuit current and the visual inspection after being subjected to a short circuit, and should generally be scrapped.
Personal Security Line Notes:
1. There are two types of short circuit: split-phase type and combination type. There are two kinds of flat terminal type and hook type wire end clamps, please indicate when users choose.
2. The cross-sectional area and length of the soft plastic copper wire are matched according to the user's specific requirements.
3, order must explain the wire size range and the use of voltage levels.
4. Insulating operating rods are selected according to the requirements of the user.
5, factory equipped with a dedicated grounding pole, the user can choose according to need.
