Standard 60km Cable Fault Pre-Locator Complete Kit | 10-inch LCD 100MHz IP54 | XHGG501B

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.

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:

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.

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.
