High voltage reel cable for bucket wheel machine

1‌Structure and Material Design‌

‌Conductor and insulation layer‌

High voltage reel cable for bucket wheel machineThe conductor is made of multiple strands of ultra-fine oxygen free bare copper wire twisted together, which complies withVDE 0295 CLASS 5/6 standard ensures high conductivity and flexibility, suitable for frequent bending conditions.

The insulation layer is made of silicone rubber or modified elastomer material, with a temperature resistance range of up to-Maintain stable electrical performance in high temperature environments from 40 ℃ to+150 ℃.

‌Sheath and protection‌

The outer sheath is made of polyurethane（Made of PUR material, it has the characteristics of abrasion resistance (scratch resistance, tear resistance), waterproofing (IP67/IP68), and oil pollution resistance, suitable for harsh environments such as ports and mines.

Inner composite tensile elements (such as galvanized steel wire rope or Kevlar fiber) to suppress core breakage or sheath delamination caused by longitudinal tension.

II‌Key performance parameters‌

‌Electrical performanceRated voltage 6/10kV, test voltage ≥ 20kV, meeting the high voltage power supply requirements.

‌mechanical properties‌：

bend radius≤ 4 times the outer diameter of the cable, resistant to bending cycles ≥ 8 million times, suitable for frequent winding scenarios.

tensile strength≥4200MPa， Wear resistance is certified by UL and IEC standards.

‌environmental adaptability‌：

High temperature resistance: long-term working temperature-40 ℃ to+105 ℃, short-term tolerance+150 ℃.

Flame retardancy: compliantThe IEC 60332-1 standard is applicable to flammable and explosive environments.

III‌Typical application scenarios‌

‌Heavy machinery equipmentPort gantry cranes, stacker reclaimers, mining bucket wheel machines and other drum power supply systems.

‌Complex working conditionsHigh temperature dust, humid salt spray, frequent mechanical vibration and other harsh environments.

4‌Installation and maintenance recommendations‌

‌Installation specifications‌：

Reserved bending radius≥ 4 times the outer diameter to avoid excessive bending and damage to the insulation layer.

Fixed end needs to be suspendedRelease internal stress within 24 hours to prevent the sheath from bulging.

‌Maintenance points‌：High voltage reel cable for bucket wheel machineRegular inspection of sheath wear, conductor breakage, and insulation resistance is required, and double-layer sheath structure is preferred for humid environments.

‌noteThis cable can be customized with a shielding layer (tin plated copper braided density ≥ 85%) or an integrated fiber optic communication module according to requirements, to meet the control needs of intelligent equipment.
