Unpack. Connect. Test. The XHGG501B ships as a complete standard kit — host, test leads, sampler, power cord, and all accessories in one case. No optional add-ons required to begin testing. Ideal for organizations that want a single SKU with predictable configuration and no procurement complexity.
The XHGG501B Cable Fault Pre-Locator is a 60km-range TDR instrument configured as a complete out-of-the-box testing system. Built around a 100MHz real-time sampling engine with a 10-inch touch LCD, it covers the full fault spectrum — low-resistance, short-circuit, open-circuit, disconnection, leakage high-resistance, and flashover high-resistance — on power cables, control cables, communication cables, street light cables, and buried wires across all cross-sections and dielectric media. Dual test methods (low-voltage pulse and high-voltage flashover) with automatic continuous sampling ensure no transient discharge event is missed. The standard kit includes everything needed to begin field testing: the host instrument, single-Q and dual-Q test leads, sampler, power cord, and safety fuse — all packed in a protective case. No separate accessory orders, no compatibility checks, no procurement follow-up. CE ISO certified.
Standard Configuration — What "Complete Kit" Means
Many cable fault locators are sold as a base unit with essential accessories listed as optional extras — the sampler, the dual-Q cable, the power cord, even the test leads. The purchasing agent quotes the base price, the technical team later discovers the missing items, and a second purchase order delays deployment by weeks.
The XHGG501B standard kit eliminates this friction. Every component required for LV pulse and HV flashover testing is included:

60km Range, 100MHz Sampling — Proven Performance
The XHGG501B's 100MHz real-time sampling engine and 0.1μs/2μs dual pulse widths cover the full range from near-end fault resolution (0.5m at 0.1μs pulse) to long-range detection (60km at 2μs wide pulse). ≤20m blind zone ensures reliable testing from the output terminals outward. Measurement error ≤±(0.5%×L+1m) provides actionable accuracy — at 30km, the fault is located within a 151m window, sufficient to direct the acoustic pinpointing crew to the correct cable segment. Automatic continuous sampling with auto-gain adjustment captures the fault reflection regardless of arc intensity variation during flashover testing.
IP54 — Built for the Field, Not the Lab
The XHGG501B's IP54-rated chassis protects against dust ingress and water splashes from any direction. Combined with an operating temperature range of -20℃ to +60℃ and ≤90% relative humidity tolerance, the instrument functions reliably in outdoor substations, roadside cable cabinets, and trench-side deployment — the environments where cable faults actually occur. The built-in lithium-ion battery supports cordless operation for open-circuit and low-resistance fault testing, eliminating the need for a generator or extension cord when mains power is unavailable.

Frequently Asked Questions
Q: What does "Complete Kit" mean — what is included in the single SKU?
The XHGG501B Complete Kit includes everything needed for cable fault pre-location in one shipment: the main TDR test unit (10-inch LCD, 100MHz, IP54), test leads, pulse coupler, HV connection cables, ground cables, charger, USB communication cable, carrying case, and user manual. No separate accessory ordering is required — unpack and begin testing immediately.
Q: How does the XHGG501B compare to the XHGG501D and XHGG502A?
The XHGG501B offers a balanced mid-range solution: 60km range (vs. 16km for 501D and 120km for 502A), 100MHz sampling with standard TDR functionality, and a 10-inch LCD in an IP54 chassis. It is the ideal choice for organizations that need more range than the entry-level 501D but don't require the ARC multi-pulse technology and 400MHz sampling of the 502 series — delivering strong cost-performance for routine cable maintenance.
Q: What test functions does the XHGG501B support?
The XHGG501B supports low-voltage pulse method for open-circuit, short-circuit, and low-resistance faults, cable length measurement, and wave velocity calibration. It also supports high-voltage flashover method (with external HV pulse generator) for high-resistance leakage and flashover faults. The complete kit includes the pulse coupler required for flashover testing, making it ready for both LV and HV test workflows.
Q: Is the XHGG501B suitable for field use in harsh environments?
Yes. The IP54-rated rugged chassis protects against dust and water splashes, and the 10-inch industrial LCD with anti-interference design provides clear visibility in outdoor conditions. The unit is designed for portable one-person operation with a robust carrying case included. Operating temperature range covers -20°C to +65°C, suitable for most global field environments.
Q: Can waveforms be exported for reporting and archival?
Yes. The XHGG501B stores test waveforms onboard with file naming capability. Via USB connection and the included PC software, waveforms can be exported for detailed analysis, report generation, and printing. For organizations requiring on-site printed reports, a compatible external thermal printer can be connected directly for instant hard-copy waveform output during field testing.
Q: What warranty and after-sales support is included?
Standard warranty is 12 months from delivery covering manufacturing defects, with lifetime technical support. Each complete kit includes a detailed user manual with wiring diagrams and waveform interpretation guidance. CE and ISO certified. Optional on-site commissioning, operator training, and extended warranty plans are available. Technical inquiries are typically answered within 24 hours.
