The SLIW52 model of insulation piercing connector, known for its durability and appealing design, features a standout element: tin-coated teeth.
As for the IPCs produced by Jera Line, they have two kinds of tin-coated teeth, the Tin-coated Copper teeth and the Tin-coated Aluminum teeth. Why there always a tin-covered teeth in the insulation piercing connector? It features following advantages:
Key advantage of tin-coated teeth:
-
Enhanced Conductivity: Tin is a highly conductive material that enhances the overall conductivity of the connector. It will minimized electrical resistance, ensuring a more efficient flow of current through the connection.
-
Protection Against Corrosion: Power connectors are exposed to various harsh environments, the need of corrosion resistance is crucial. Tin will react with oxygen preferentially to form a protective film, thus preventing the interior from corrosion.
-
Improved Durability and Reliability: The tin coating also reduces wear on the teeth during repeated use, ensuring that the IPC remains functional for an extended period.
-
Smooth Piercing Process:The smooth surface of tin-coated teeth enhances the efficiency of the piercing process.

What Kind of Teeth Does Jera Line Use for the Substitute Product of SLIW52?
Jera Line is a leading manufacturer specialized in connectors for low and medium voltage power lines. There are three types of insulation piercing connector that can match the function of SLIW52.

-
Suitable for both AL and CU conductors
-
High Corrosion Resistance was tested by salt spray and fog testing equipment.
-
It is suitable for harsh environments and can prevent humidity, UV radiation and small impacts.
-
Competitive price with small brand cost.
The differences between Tin-coated Copper and Tin-coated Aluminum in insulation piercing connectors:
-
Tin-coated Copper teeth: It has a higher density than aluminum and is lighter in overall mass, but it also offers better heat resistance. It is suitable for power lines that need high temperature resistance. Also, the copper teeth have better electrical performance than the aluminum teeth but come with a higher cost.
-
Tin-coated Aluminum teeth: It is lighter than copper teeth, which can reduce the load on the cable, but its heat resistance is not as good as that of copper teeth. But because of its high cost-efficiency, it is more widely used. But because of the high cost-efficiency of tin-coated aluminum teeth, they are more widely used.
Jera Line produce both two types of the teeth, as well as Brass teeth and Aluminum teeth for different requirements.
