Application
Deep Well Submersible Pumps: Ideal for installations where space is limited and a round cable might get snagged.
Irrigation Systems: Powering large-scale agricultural pumps in boreholes or reservoirs.
Mining Drainage: Reliable power delivery for dewatering pumps in narrow shafts.
Industrial Water Supply: Used in municipal water systems for high-pressure submersible motor connections.

FAQ
1. What unique mechanical advantage does the flat parallel geometry offer for submersible pumps?
Space-Saving Slim Profile:
Unlike standard round cables that easily twist or get snagged inside narrow borehole casings, our JHSB / H07RN4-F cable features a precision-extruded flat parallel core alignment. This low-profile geometry minimizes the external dimensions, allowing the cable to fit effortlessly into the tight clearance border between the submersible pump body and the deep-well casing. The parallel design also eliminates internal rotational friction, extending the cable’s operational lifespan in heavy-vibration pump environments.
2. How does the EPR insulation maintain perfect dielectric stability under high underground water pressure?
Elite Hydrostatic Moisture Barrier:
Deep well installations subject submersed cables to extreme hydrostatic pressure, which can force moisture into regular PVC lines, causing rapid water treeing breakdown. Our flat pump cable addresses this failure bottleneck by insulating each Class 5 core with premium-grade, water-resistant Ethylene Propylene Rubber (EPR). This advanced polymer compound exhibits near-zero water absorption and exceptional dielectric strength, preserving a perfect, leak-free power supply across decades of continuous submersion.
3. What are the explicit technical distinctions between JHSB and standard H07RN4-F specifications?
Multi-Standard Engineering Equivalence:
The nomenclature frameworks align tightly with specific regional standard metrics to fit international infrastructure tenders: ‘JHSB’ satisfies China’s national coal mine and water-intake guidelines for flat waterproof rubber flexible cords; while ‘H07RN4-F’ directly complies with rigorous European VDE and EN 50525-2-21 harmonization rules rated explicitly for heavy-duty 450/750 V distribution. Utilizing these cross-referenced designations ensures frictionless regulatory compliance for global engineering projects.
4. Can this flat rubber flexible cable withstand aggressive chemicals or minerals in groundwater?
Chemically Immune Heavy-Duty Jacket:
Yes. Natural groundwater and deep mining drainage channels are heavily saturated with organic acids, sulfur, active alkaline minerals, and non-corrosive machine grease. Our H07RN4-F / JHSB wire is encased in a vulcanized, heavy-duty synthetic rubber outer jacket. This resilient elastic shell provides high tensile pulling strength for long vertical drops, resists severe mechanical tearing against rock walls, and shields the core matrix from corrosive mineral fluids.
5. What wholesale core variations and B2B project logistics packaging does ZHONGYI CABLE guarantee?
Rigorous B2B Supply Logistics & Drum Security:
As an established direct factory cable manufacturer, we supply flat submersible cables in standard 2-core and 3-core configurations, spanning continuous cross-sections from 1.5 mm² up to heavy-duty 240 mm² distribution matrices. To protect the supple rubber protective jacket and maintain strict edge alignment during long-distance maritime transit, wholesale orders are wound securely on heavy-duty wooden drums, fully backed by complete factory Type Test Reports.
