In modern cable industry,copper-plastic composite tape is an indispensable key material. It integrates OOO armor protection, electromagnetic shielding and insulation functions, and is widely used in power, communication and control cables, providing multiple guarantees for the stable and reliable operation of cables .
Introduction to core advantages
Unbreakable mechanical protection (armor function)
This composite tape usually takes high-strength plastic film (such as PET) as the base tape, with high-conductivity plain copper foil compounded on both sides. This “steel-flexible combination” structure provides excellent mechanical armor protection for the cable. It can effectively resist the external pressure, impact and puncture by sharp objects that the cable experiences during laying and use, prevent damage to the internal insulation and core, significantly extend the service life of the cable, and is especially suitable for “Bury directly” Harsh environments such as pipe threading.
Outstanding electromagnetic shielding performance (shielding function)
Its continuous copper layer forms a complete sealed shielding layer, creating an effective “” Faraday cage” Effect. This can effectively block the interference of external high-frequency electromagnetic waves (such as radio waves and base station signals) on the signals transmitted inside the cable, and at the same time prevent the internal signals of the cable from radiating outward, ensuring the integrity and confidentiality of data communication. This is of vital importance for weak current signal lines, data communication cables and instrument control cables.
Reliable insulation and moisture-proof barrier (insulation function)
The plastic film, which is a component of the composite tape, itself has good insulating properties. When the composite tape is longitudinally wrapped in Cable core After the outer lap joint is sealed, it not only provides an additional insulating layer but also forms a solid Moisture-proof barrier It can effectively prevent the invasion of water vapor and chemically corrosive substances, protecting the conductor Protected from corrosion Ensure the long-term stability of electrical performance.
Summary and Application
In conclusion, armored shielding insulated copper-plastic composite tape is a multi-functional and high-performance product Cable materials . It will Armored The intensity, Block The efficiency and Insulation The perfect combination of reliability makes it an ideal choice for manufacturing high-quality communication cables, signal control cables, instrument cables and medium and low voltage power cables, safeguarding the security of modern power and information transmission networks.
