RHZ1(YJLV) 8.7/15kV(Al/XLPE/CTS/LSZH)

Application

The RHZ1 medium voltage power cable serves multiple critical functions in electrical infrastructure. This cable works efficiently in power distribution networks across various environments. You can install it for connecting generation units to main power systems. The cable also handles plant and process connections in industrial facilities.

Installation flexibility makes this cable suitable for different environments. You can lay it directly underground for permanent installations. The cable performs well in outdoor applications where weather resistance matters. Indoor installations benefit from its compact design and safety features. Cable duct installations provide additional protection and organization.

Description

Gongniu Cable manufactures the RHZ1 using advanced materials and proven construction methods. The cable features an aluminum conductor that provides excellent electrical conductivity. Class 2 circular compacted conductors ensure reliable power transmission with minimal losses.

The insulation system uses Cross-Linked Polyethylene (XLPE) technology. This material offers superior electrical properties and long-term durability. Non-metallic semi-conducting compounds create effective conductor and insulation screens. These screens ensure uniform electric field distribution and enhanced safety.

Copper tape screening provides electromagnetic protection and fault current handling. The metallic screen can also use copper wire depending on specific requirements. Gongniu Cable selects the appropriate screening method based on application needs.

The outer sheath uses Polyvinyl (PO) compounds in various formulations. Available options include DMZ1, DMZ2, LSOH, and LSZH materials. Standard colors are black or red to meet different installation requirements.

Key Characteristics

This cable delivers excellent electrical and mechanical performance. The low dielectric loss factor ensures efficient power transmission with minimal energy waste. High insulation resistance maintains system reliability over extended periods.

The PO outer sheath provides strong resistance to UV radiation, oil exposure, and physical abrasion. These properties extend cable life in challenging environments. ZD Cable designs different cable structures and materials to meet specific application requirements.
