What impact does the high-density PE insulation layer have on the signal transmission efficiency and electromagnetic interference protection of the Patch Cord?

The dielectric constant of the insulating material is a key parameter that determines the capacitive characteristics of the Patch Cord. High-density PE has a relatively low dielectric constant, which means that when a signal propagates through the material, it propagates faster and the capacitance effect is relatively small. This feature helps reduce signal loss and delay during transmission, which is particularly advantageous when transmitting over long distances or at high speeds.
Dielectric loss is an inevitable energy loss when a signal propagates in an insulating material. High-density PE is used as an insulating layer material with relatively low dielectric loss, and the signal can maintain higher integrity during transmission. Low dielectric loss helps reduce signal distortion, thereby improving the quality of signal transmission. This is especially important for application scenarios that require high-fidelity transmission, such as audio, video, and data communications.
In high-frequency signal transmission, the performance of insulating materials has a more significant impact on signal quality. High-density PE has excellent frequency response characteristics and can reduce the skin effect of high-frequency signals. The skin effect refers to the phenomenon that when a high-frequency signal propagates in a conductor, the signal mainly flows on the surface of the conductor. This phenomenon results in increased impedance and signal loss. The excellent performance of high-density PE helps to reduce this impact, thereby improving the transmission efficiency of high-frequency signals.
Although high-density PE itself does not directly provide electromagnetic shielding function, it has good insulation performance as a barrier between the internal conductor of the cable and the external environment. This performance helps reduce the leakage and interference of electromagnetic waves, thereby protecting the stability of signal transmission. This shielding effect is important in application scenarios with complex electromagnetic environments, such as data centers, industrial control and other fields.
High-density PE not only has good insulation properties, but also has excellent chemical stability and weather resistance. It can resist erosion from various environmental factors such as moisture, corrosion, etc. These features help maintain the long-term stability and durability of the cable, thereby indirectly improving electromagnetic interference protection. Under harsh environmental conditions, such as high temperature, low temperature, humidity, etc., the excellent performance of high-density PE can ensure the normal operation of the cable and protect signal transmission from being affected.
