Materials and Design of LMR-2200-7YFZ Coaxial Cable

The LMR-2200-7YFZ is a high-performance coaxial cable engineered for reliable signal transmission across a wide range of applications, including telecommunications, broadcasting, and wireless infrastructure. Its superior performance stems from a carefully balanced design and the use of premium materials that work in harmony to minimize signal loss, resist environmental stress, and ensure long-term durability.

Core Components and Material Composition

Center Conductor

The center conductor is the primary pathway for signal transmission—functioning much like a high-speed data highway. In the LMR-2200-7YFZ, this conductor is typically constructed from high-purity copper or copper-clad aluminum (CCA), chosen for excellent electrical conductivity and low resistance.

Copper ensures minimal signal attenuation, making it ideal for long-distance runs and high-frequency applications. The precise diameter and consistency of the conductor are critical for maintaining impedance stability (typically 50 ohms), which is essential for preventing signal reflections and ensuring clean data transfer.

Dielcetric Insulation

Surrounding the center conductor is a precision-engineered layer of dielectric insulation, usually made from foamed polyethylene (FPE) or similar low-loss materials. This layer serves multiple vital functions: it maintains consistent spacing between the center conductor and the shield, prevents electrical contact, and significantly reduces signal loss.

Foamed insulation offers a lower dielectric constant, which improves signal velocity and reduces attenuation. It also acts as a buffer against electromagnetic interference (EMI), much like soundproofing in a studio, ensuring signal integrity even in electrically noisy environments.

Electromagnetic Shielding

The shielding system is the backbone of interference protection in the LMR-2200-7YFZ. It typically consists of multiple layers: a foil shield (aluminum-polyester tape) for 100% coverage and a high-density braided copper mesh for flexibility and durability.

This dual-layer design provides exceptional shielding effectiveness (often exceeding 95 dB), blocking external RF interference and preventing signal leakage. The braid also enhances mechanical strength and grounding reliability, making the cable suitable for both indoor and outdoor installations where EMI from power lines, motors, or radio sources is a concern.

Outer Jacket

The outer jacket is the first line of defense against physical and environmental damage. For the LMR-2200-7YFZ, jackets are commonly made from UV-resistant polyethylene (PE) for outdoor use or low-smoke zero-halogen (LSZH) compounds for indoor plenum spaces.

Outdoor variants are designed to withstand extreme temperatures, moisture, UV radiation, and abrasion. The jacket also provides crush resistance and flexibility, allowing the cable to be routed through conduits or buried directly in the ground when properly protected. Color-coding (often black or gray) aids in identification and professional installation.
