38mm Through Bore Explosion-Proof Slip Ring | 22 Circuits 10A, Ex d IIB T4 Gb

Ingiant Self-Developed Winch Explosion-Proof Slip Ring

The DHK038F-22-10A Explosion-Proof Slip Ring was engineered specifically to close this gap. Below are its core technical parameters:

This professional winch explosion-proof slip ring is independently developed and precisely manufactured by Jiujiang Ingiant technology Co., Ltd.. Tailored for high-risk mining and industrial winch conditions, it adopts core configurations including EX d ⅡB T4 Gb explosion-proof grade, 38mm standard inner diameter, 22 channels / 10A per channel, 304 stainless steel structure and IP65 high protection grade, solving all industry pain points and supporting 24-hour continuous safe operation of winches in explosive environments.

1. EX d ⅡB T4 Gb Explosion-Proof Grade — Eliminate Explosion Risks Fundamentally

Adopting professional EX d flameproof structure, this slip ring is applicable to Zone ⅡB flammable gas explosive environments. The maximum surface temperature is controlled within 135℃ (T4), far lower than the ignition point of common mining flammable gases. With Gb high-level equipment protection, it operates stably and safely in hazardous areas, fully complying with international mining explosion-proof standards and completely avoiding explosion accidents caused by electric sparks and overheating.

2. 22 Channels & 10A Rated Current — Stable Transmission & Perfect Working Condition Adaptation

22 independent channels support simultaneous and isolated transmission of winch power supply, control signals and sensor signals without mutual interference. The 10A per-channel rated current fully matches the conventional operating current of industrial winches. Adopting high-precision wear-resistant conductive contacts, it resists vibration and rotational wear, eliminating power cut-off and signal drift during high-frequency operation, and ensuring stable performance of winch start-stop, speed regulation and braking systems.

3. 38mm Standard Inner Diameter — Universal Compatibility & Easy Installation

Designed with a 38mm industry-standard inner diameter, it perfectly fits the rotating shaft of mainstream winch models. No mechanical modification or customized processing is required. It supports direct replacement of old slip rings, compatible with both new and existing winch equipment, effectively reducing equipment renovation cost and installation difficulty.

4. 304 Stainless Steel Structure — Anti-Corrosion, Anti-Wear & Extended Service Life

The whole machine adopts 304 stainless steel structure, featuring excellent acid and alkali resistance, rust resistance and mechanical wear resistance. It effectively resists moisture erosion, dust corrosion and outdoor weathering in mining sites, avoiding structural deformation and aging. It greatly prolongs service life, reduces replacement frequency and cuts long-term operation and maintenance costs.

5. IP65 Full Sealing Protection — Block Dust & Moisture Intrusion

Equipped with IP65 full sealing protection, the slip ring achieves complete dust prevention and splash-proof performance. It adapts to extreme mining conditions including heavy dust, high humidity and splashing water. The fully sealed structure protects internal conductive and insulating components from damage, eliminating electric leakage, short circuit and burnout failures, realizing 24-hour uninterrupted stable operation and minimizing downtime rate.

4. Core Product Value

With years of professional experience in precision slip ring R&D and manufacturing, Jiujiang Ingiant Technology Co., Ltd. provides this winch-specific explosion-proof slip ring with six core advantages: standard explosion-proof safety, stable signal transmission, high-level protection, superior corrosion resistance, universal compatibility and low maintenance cost. It fundamentally solves the common industry problems of traditional slip rings, fully meeting the high-standard continuous operation demands of mining winches in South Africa and global mining sites, and serving as a reliable core component for safe, efficient and low-cost mining production.
