“KANZACC anga” Sulfurization Resistant Silver Plating Film
This is the new type of sulfurization resistant silver plating
film which maintains sulfulization protection function evenwith high temperature treatment. The film prevents thedegradation of performance due to sulfurization, such as
the increase in contact resistance and the reduction inHeat

High Hardness and Abrasion Resistant Silver Plating Film
“KANZACC anga-U”
This is the new silver plating film with a higher hardness
and a higher resistance to abrasion compared to commonly used silver plating film. In addition, this film is difficult to sulfurize and most sulfide discoloration does notoccur. Therefore, this film perfectly suites the film for connectors and switches with repeated insertions for long
period of time.

Lightweight and High-Performance Tin Coated Aluminum Wire
“KANZACC ALC”
This is the lightweight and high-performance wire with tin
coating on aluminum wire surface. The easy solderingfeature makes possible end face encasing for corrosion
prevention.
KANZACC ALC can be implemented in a wide range ofapplication, such as possible soldering of an aluminum
wire which saves 30% of weight compared to copper wire

cable and lightweight possible soldering of a magnet wirewith insulated coating “ALC-fine”.
Use application: Automotive cables, Robots cables,
Magnet wire, Lightweight coils, Litz wires, Wiring materials etc.
Feature: ①Weight reduction ②Soldering possible aluminum wires ③Corrosion reduction

“KANZACC COFT” for Electric Cables, Lightweight andHigh Strength Cables with Metalized Aramid Wireor Metalized Carbon Fiber
These are electric cables using aramid fiber which hasless elasticity, lightweight and high strength features.
Each aramid fiber is metal coated and exhibits tremendous flexibility. Copper, tin and silver can be selected forfiber coating material depending on the application.

Carbon fiber can be coated with these metals in the sameway as aramid fiber.
Usage application: Robots cables, Control cables etc.
Feature: ①Lightweight and high strength cables ②High
flexibility cables ③Perfect suits for signal cables

Compact Multi-core Conductor for High-Frequency Current“KANZACC enatube”
This cable consists of insulated wire strands and copper
tube covering the strands. Hence, the cable forms multicore rectangular cable. A single wire increases the electrical resistance with high frequency current because of theskin effect. The electrical resistance increase can beimproved by using multi core cables. Further more, dense
structure of this cable reduces 25% of the cross sectional

area in comparison with the same performance litz cable.
“KANZACC enatube” provides a compact designing.
Usage application: Motors, Transformers, Inverters,
Induction heaters etc.
Feature: ①Compact conductor for high frequency current②Lighten AC resistance increase ③Efficiency increaseand energy saving of equipments

High frequency-Current Supply Cable for Noncontact Charging
Systems for EVs “KANZACC EMIC-One”
Multiple insulated conductor wires covered with corrugated metallic tube forms this multi core buried cable. This
cable supplies a high frequency high current from thepower panels of noncontact charging system to the primary coil on the ground. By using multiple conductors,
increase in AC resistance is improved and efficiency isincreased.
A connector is attached at the cable end and very easily connected. Further more, ground burial is very easy
because of the corrugating, so installation work is drastically made easier.
Usage application: Noncontact charging systems etc.
Feature: ①High efficiency cable lightening AC resistanceincrease ②Easy installation by corrugating and connector
