About Telecommunication Cables Jelly Filled Cables
Telecommunication Cables Jelly Filled Cables are filled with special type of jelly with pressure pimp to make it resistance from moisture. It contains high quality petroleum jelly that is capable of providing water resistance, fire resistance and excellent insulation for each pair. In order to make these cables weather and high temperature proof, aluminum mailor foil is widely used with polyester film in their fabrication. Conforming to industrial quality standards these Telecommunication Cables Jelly Filled Cables are mainly used for underground telephone cabling.
Superior Moisture and Weather ProtectionJelly Filled Cables utilize a specially formulated, non-hygroscopic petroleum jelly to prevent water ingress. Combined with a UV-resistant black polyethylene sheath and self-extinguishing properties, they are engineered for longevity and dependable operation in demanding outdoor environments.
Exceptional Signal Integrity and PerformanceWith excellent EMI/RFI immunity, low capacitance variation, and uniform impedance, these cables maintain superior signal quality. The use of solid annealed copper conductors, high-density PE insulation, and precise shielding ensures data and voice communications remain crisp and clear over long distances.
Flexible Applications and Robust ConstructionSuitable for telecommunication exchanges, outdoor networks, and duct installations, these jelly-filled cables come in multiple pair counts and lengths, accommodating diverse project needs. Armored and non-armored types, backed by rigorous standards, deliver versatile reliability in critical communication infrastructure.
FAQs of Telecommunication Cables Jelly Filled Cables:
Q: How does the jelly filling enhance the cables performance?
A: The non-hygroscopic petroleum jelly used as the filling compound prevents moisture from entering the cable, effectively protecting the inner conductors from water-induced damage and oxidation. This results in long-term, reliable signal transmission, even in environments prone to dampness or water exposure.
Q: What benefits do jelly filled cables offer for telecommunication installations?
A: These cables provide robust moisture resistance, excellent immunity to electromagnetic (EMI) and radio frequency (RFI) interference, and strong UV and fire resistance. This makes them ideal for outdoor, direct burial, aerial, and duct installations where environmental conditions can compromise ordinary cables.
Q: When should I choose an armored version of the jelly filled cable?
A: An armored version with steel tape should be selected for installations that require extra physical protection, such as direct burial in rocky areas or locations where mechanical stress is expected. The armor significantly improves the cables durability against external impacts.
Q: Where are these jelly filled cables typically used?
A: These cables are commonly used in telephone exchanges, outdoor telecommunication networks, direct burial applications, aerial pathways, and duct installations. Their rugged construction makes them suitable for both urban infrastructure and remote area deployments.
Q: What is the process for identifying cable pairs during installation?
A: Each pair within the cable is both numbered and color-coded following industry standards, ensuring straightforward identification and organization during installation, maintenance, or splicing. This minimizes errors and speeds up the wiring process.
Q: How is the cable protected against UV radiation and fire hazards?
A: A black polyethylene (PE) sheath offers strong UV protection for outdoor installations, while the cables construction meets fire retardant and self-extinguishing standards. This dual protection maintains cable integrity under various environmental stresses.
Q: What are the standard lengths and sizes available for these cables?
A: Jelly filled telecommunication cables are available in lengths of 100m, 305m, 500m, and 1000m, with custom lengths offered as needed. Common conductor diameters include 0.4mm and 0.5mm, and pair counts range from 2 to 100 pairs, accommodating diverse installation requirements.
