Introduction

The КГЭШ and КГЭШ-Т cables are top-tier solutions for connecting coal combines, mobile machinery, and other equipment in underground mining operations. These cables are engineered to handle the rigorous demands of mining environments, ensuring reliability and safety with a nominal voltage of up to 1140V.

Construction Elements

Conductive Core (Токопроводящая жила)

The conductive core is made of class 5 flexible copper or tinned copper wires. This structure ensures excellent conductivity and flexibility, crucial for the dynamic and harsh conditions found in mining operations.

Insulation (Изоляция)

The main conductors' insulation varies depending on the cable type:

For КГЭШ and КГЭШ-Т cables, the insulation is made from a rubber blend based on natural rubber, combined with butadiene and other synthetic rubbers. This combination offers superior durability and electrical insulation.

For КГЭТШ and КГЭТШ-Т cables, the insulation uses high-heat-resistant rubber based on ethylene-propylene rubbers, providing enhanced thermal stability.

Insulation Screen (Экран по изоляции)

The insulation screen is made from conductive rubber. This feature is essential as it reduces electromagnetic interference and ensures the electrical safety of the cable.

Ground Conductor (Жила заземления)

The ground conductor is composed of flexible copper or tinned copper wires, providing an essential path for grounding, which enhances overall system safety.

Auxiliary Conductor Group (Группа вспомогательных жил)

These additional conductors are designed to support various auxiliary functions, ensuring the cable's versatility and reliability in complex mining operations.

Wrapping (Обмотка)

The wrapping consists of synthetic film or non-woven fabric, offering an extra layer of mechanical protection and stability.

Sheath (Оболочка)

The outer sheath is made from oil-resistant rubber that does not propagate combustion. This sheath ensures the cable's durability in the presence of oils and fuels, which are common in mining environments. The tropical version, КГЭШ-Т, is resistant to mold and fungi, making it suitable for humid and tropical climates.
