Insulation Piercing Clamp Made Simple: What You Need to Know

Insulation puncture clips can be divided into 1KV, 10KV, 20KV insulation puncture clips according to voltage classification.

According to the function classification, it can be divided into ordinary insulation puncture clip, electric inspection grounding insulation

puncture clip, lightning protection arc insulation puncture clip, fireproof insulation puncture clip!

The branch technology of cable piercing clip cleverly cooperates with the power supply mode of the cable. With its unique advantages,

it provides a fast, simple and reliable connection for the cable branch, and completely solves various technical problems of the cable branch,

so it may become the most developed Promising power line branching technology. The key technology of the cable piercing branch is the

piercing and sealing branch structure; and using the new achievements of modern technology, adding strong fiber plastics and special alloys

is used to improve the mechanical strength, waterproof and anti-corrosion performance of the branch joint and the electrical contact

performance of the branch. Performance parameters of different types of wire clips. Compared with the traditional cable connection method

(split box or cable crimping tube), the power supply performance has the following advantages:

(1) The insulation piercing clip does not need to cut off the main cable, and does not need to cut the insulation layer inside the cable. It can

be branched at any position of the cable without damaging the mechanical and electrical properties of the cable. In the past, the use of cables

in the distribution lines in the building required a lot of waste of return cables. The branches needed to set up terminal boxes, cut off the main

cables, or completely strip the insulation of the main cables, and use crimp joints as branches, which was labor-intensive and material-intensive.

and greatly reduce the cable performance. Using the puncture wire clip, an unskilled worker can complete hundreds of branch heads in one

working day, while using the crimping branch head, only a few branch heads can be made in one working day.
(2) The electrical performance of the insulation piercing clip is extremely high, the dielectric strength is up to 6KV, and it can withstand the

current impact of 15KA. The joint heats up very little, and the current experiment shows that the heat generation of the puncture clip is smaller

than that of the same diameter wire. Any traditional cable branch It is difficult to meet the above standards.

(3) The mechanical strength of the insulation puncture clip is high, and the shell is made of plastic with added strong fiber, which is waterproof,

anti-corrosion, anti-corrosion, anti-mechanical tension, and anti-distortion. The traditional branch adopts crimping branch, and the tensile

strength of the machine is very low, and it is afraid of twisting.

(4) The insulation puncture clip is made of special alloy, and with the sealing structure, there is no air and water entering, so there is no galvanic

corrosion. Suitable for copper-aluminum transition or copper-aluminum butt joint.

(5) The installation of the insulation puncture wire clip is extremely simple, with torque bolts for constant puncture pressure, and good electrical

contact is determined by mechanical means, the quality is reliable, and it is not easily affected by human factors. The traditional cable branch head

is inconvenient to install, time-consuming and labor-intensive, and workers need special training. Heat-shrinkable materials are used for insulation,

and special tools are required. It is easily affected by human factors and the quality of materials.

(6) The inspection of the connection quality of the insulation piercing clip is intuitive and convenient, just observe whether the torque nut is unscrewed,

and whether the position of the main and branch conductors is appropriate, and the service life is more than 35 years, and no maintenance is required.

The installation quality of the traditional cable branch head cannot be pre-tested, the service life is relatively short, and the failure rate is high.

(7) The insulation piercing clip is detachable, suitable for the connection of different diameter wires, the scope of application is 1.5 ~ 400mm2, the scope

of application is clearly marked on the product, and can be selected arbitrarily.

Of course, the shaft power supply method of cable + puncture wire clip also has its shortcomings. First, the maximum wire diameter of the current

puncture wire clip is 400 mm2. The power supply capacity is smaller than that of the busway, and the second is how to make the layout of the

wire clip more beautiful.
