Data line protectors
Data line protectors from Shenzhen Techwin Lightning Technologies Co., Ltd are surge protection devices designed for Ethernet networks, safeguarding CAT5e, CAT6, and other data lines against lightning-induced voltage spikes and electrostatic discharge. These units integrate gas discharge tubes and TVS diodes in dual-stage protection circuits, rated for 10/100/1000 Mbps transmission. Each model is built to meet industrial environmental standards and is compatible with standard RJ45 connectors.
The protectors are available in multiple variants based on operating voltage: 5V, 12V, and 36V models, each with corresponding peak discharge currents up to 5 kA. Protection levels range from 25V line-to-line to 160V line-to-PE under 8/20 µs surge conditions. Insertion loss is kept below 0.5 dB, and response time is under 5 ns. Units are constructed with flame-retardant housing and operate reliably between -40°C and 85°C.
These protectors are used in industrial control systems, telecom base stations, network switches, and outdoor surveillance installations where lightning exposure is common. Buyers include system integrators, network equipment manufacturers, and infrastructure contractors. Units are packaged in anti-static bags with bulk quantities available in cartons of 100 or 500 pieces. Trade terms are typically FOB Shenzhen, with minimum order quantities starting at 500 pieces per model.

Sourcing Data line protectors from Shenzhen Techwin Lightning Technologies Co., Ltd - China Import Guide
Before ordering, confirm the exact model number and its electrical ratings match your application. Request test reports for discharge current, protection level, and insertion loss. Verify that the protector is compatible with your network speed (10/100/1000 Mbps) and that the connector type matches your cabling. Do not assume all models are interchangeable.
Logistics are typically FOB Shenzhen port. Lead time is 15 - 25 days after payment, depending on order size and model availability. Payment is commonly via T/T in advance or L/C. Incoterms should be clearly defined in the contract. Buyers must confirm packaging is anti-static and moisture-sealed for long transit times.
Quality checks should include visual inspection for damaged housings, connector alignment, and label accuracy. Test a sample unit with a surge generator to confirm clamping voltage and response time. Request a certificate of conformity for each batch. Retain a sample from each shipment for future reference in case of field failures.
