Product Overview

Damage to the sheath and damp‑aged insulation layers of underground cable segments will cause continuous drop of insulation resistance, which may further develop into ground faults and line tripping. Conventional insulation testing requires power‑off offline tests and cannot realize live‑line real‑time online monitoring of cable insulation status.

The Haosheng HS‑RT‑WB cable insulation‑monitoring device collects sheath insulation resistance and surface temperature of cables under live‑line operating conditions, enabling synchronous acquisition of 1‑channel resistance and 1‑channel temperature. Equipped with dual‑mode RS485 and WIFI by default, with 4G available for custom configuration. Adopting standard industrial communication protocols, it can seamlessly connect with third‑party industrial‑control systems and cable operation‑maintenance management platforms without binding to proprietary backend systems. Rated IP67 for protection, it adapts to complex working conditions such as buried installation and humid environments. Its low‑power design supports long‑term operation. It tracks insulation degradation trends of cables in real‑time, predicts insulation breakdown risks in advance and facilitates condition‑based maintenance for cables.

Core Product Advantages

1. Live‑line Online Insulation Measurement, No Power‑off Operation Required
   No power cut‑off or withstand‑voltage test is needed. It continuously monitors sheath insulation resistance while cables are in normal service without interrupting power supply. It greatly reduces power‑off maintenance frequency and mitigates interference to production and power supply caused by maintenance work.
   
2. Dual‑dimensional Monitoring of Insulation & Temperature for Accurate Aging Assessment
   High‑precision acquisition of insulation resistance ranging from 10 kΩ to 5 MΩ together with synchronous temperature monitoring. Combined with temperature variation data, multiple fault types including cable dampness, sheath damage and insulation ageing can be comprehensively judged for accurate hazard location, providing reliable data support for condition‑based maintenance.
   
3. Standardized Multi‑mode Communication for Flexible Third‑party‑system Integration
   Dual‑mode RS485 and WIFI are standard; 4G is optional upon request. The RS485 interface complies with Modbus‑RTU industrial protocol and can directly connect to power industrial‑control systems such as PLC and SCADA. WIFI supports universal IoT protocols including MQTT for flexible integration with diverse third‑party monitoring platforms and data middle‑platforms. Local commissioning via Bluetooth is also supported for enclosed sites such as underground utility tunnels and cable trenches without public‑network signals, facilitating on‑site operation and maintenance.
   
4. Compact Form Factor for Simple & Easy Installation
   Featuring a small integrated body, the device can be strapped and fixed directly onto the outer cable sheath without damaging original cable structures. A single worker can finish rapid deployment. It delivers low construction difficulty and low retrofitting cost, suitable for batch renovation of existing cable lines.
   
5. IP67 Industrial‑grade Protection for Underground Complex Working Conditions
   With IP67 dust‑proof and water‑proof rating, it resists high/low temperature and corrosion. Passing both EMC electromagnetic‑compatibility and neutral salt‑spray industrial certifications, it performs stable long‑term data acquisition in harsh underground environments including soil burial, water immersion, high humidity and heavy dust.
   
6. Full‑dimensional Customization to Meet Diversified Project Requirements
   Full‑range ODM/OEM services are supported. Extra voltage and current acquisition channels can be added and resistance measuring ranges can be adjusted on demand. Customizable items include communication protocols, device appearance, silk‑screen LOGO and neutral packaging. Secondary software‑hardware development is available for seamless integration with various third‑party cable operation‑maintenance systems. Both small‑batch and mass‑volume orders are acceptable.
