Concentric Wire
The concentric wire It is made up of one or more layers of concentrically twisted wires..
The electrical loss of ZMS concentric cable is small. Its structure greatly reduces electromagnetic interference. Besides, has a smaller outer diameter and lighter weight.
ZMS we manufacture various types of concentric cables 3×12, 2×6, 2×4, cable antifraude, etc. If you need to customize a specific cable, we can provide professional production.

Structure:
Its materials are CU/AL. has at least 2 drivers.
XLPE / PVC
electrical materials, one of the conductors is the center, the other conductors surround this center.
Main Types of Concentric Cable
concentric wires 6 mm and concentric cables 4 mm of 600/1000V are used in electrical services is used as an electrical service for the distribution and transmission of electricity to shopping centers, residential and rural areas.
ZMS three core concentric wires include 3 concentric wire×8, the concentric cable 3×10 and the concentric cable 3×12. They are suitable for aerial laying, direct burial and pipe laying.
ZMS Round Concentric Wires Meet ASTM-B Standards, ASTM-D y UL. It is concentric cable 6mm it is insulated with XLPE and has good flame retardant property.
Aluminum anti-fraud cable is often used at service entrances for power transmission. ZMS single-phase anti-fraud cable is useful to prevent power theft.
You can find the concentric cables 2×4, 2×6, 2×8, 2×10, 2×12 in the range of ZMS concentric products of 2 cores. If you have other structural requirements, we can also offer you a tailor-made service.
What are concentric conductors used for??
Since the three isolated cores of the concentric cable are arranged in an equilateral triangle, its three-phase load cores form a balanced and symmetrical structure.
This makes the AC resistance of the cores equal. This greatly reduces mutual electromagnetic interference caused by unbalanced three-phase loads..
The positive and negative sequence impedance of each core is close to zero, which reduces mutual electromagnetic interference. And therefore, It has strong anti-interference ability. A core of the concentric cable can be used as the fourth conductor of the zero line and as the cable shielding.
Since there is no separate zero line, the amount of copper used is reduced. This means effective savings on cable costs. Besides, the outer diameter and weight of the power cables are reduced.
ZMS offers concentric cables in various sizes: 2×4, 2×6, 2×8, 2×10, 3×6, 3×8, 3×10, 3×12, etc. ZMS we also manufacture the marine coaxial cables.
Advantages of Concentric Cables
- Concentric conductors have a positive impedance (reverse) and low and uniform zero sequence, which contributes to improving the quality of food.
- ZMS single-phase concentric cables have a much lower reactance value in zero-sequence operation than the fourth core of ordinary multi-conductor cables.. Facilitates sensitive activation of automatic short-circuit protection devices. Safe operation of cable-related equipment can be ensured.
- ZMS 2x6 concentric cables have high resistance to electromagnetic interference and lightning.
- Concentric five conductor power cables are suitable for three-phase five-wire power distribution systems.
- 2x4 concentric cables have excellent electrical properties. Fire resistant or flame retardant materials can be used to improve their fire resistant properties..
