Delta Lightning Arrestors

What Delta Lightning Arrestors does

Delta Lightning Arrestors is a privately held, founder-owned manufacturer of lightning and surge protection devices headquartered in Big Spring, Texas. Founded in 1971 by Mike Craddock, the inventor of the silicon oxide varistor (SOV) arrestor, the company designs and builds analog surge protection hardware whose core differentiator is the elimination of the spark gap and series resistor found in conventional valve-type arrestors dating to 1935. The SOV design uses metal electrodes separated by a silicon oxide compound that ionizes under high voltage to conduct surge current to ground and recombines when voltage normalizes, enabling faster discharge, bi-directional conduction, and fail-open behavior. Delta's product portfolio spans LA Series silicon oxide arrestors (residential through 2300V high-voltage), MO Series MOV-based arrestors, CA Series surge capacitors, cathodic protectors, telephone/data line protectors, and bundled TLC Total Lightning Control packages. Unit prices range from $48 for entry-level residential models to $2,400 for complete lightning control systems.

The company's business model is straightforward direct-to-consumer hardware sales. Orders are accepted by phone, fax, email, or via the company website (deltala.com) and shipped within the continental United States only. Payment is accepted via credit card, money order, or check; there is no subscription, recurring service, or licensing component to revenue. Customer segments are vertical-driven and span residential homeowners, PV/solar installers, oil and gas operators (the original end-market for the invention), water well and submersible pump operators, HVAC users, and commercial electronics buyers.

Delta operates as a bootstrapped, independent business with no disclosed institutional investors, no funding rounds, no acquisitions or divestitures, no partnerships, and no parent company. The technology is held as a trade secret rather than via published patents, and the company appears to remain under founder control, with a headcount of 11–50 employees. Geographic footprint is restricted to North America (continental US), and marketing is conducted almost entirely through the company's own website and direct contact channels rather than through distributors, retailers, or paid media.

Core offering

Delta Lightning Arrestors manufactures and sells silicon oxide varistor (SOV) lightning arrestors, MOV-based surge arrestors, surge capacitors, and combined lightning control packages for residential, commercial, industrial, oilfield, and photovoltaic applications. The company sells physical hardware devices directly to end users via phone, fax, email, and website, with unit prices ranging from $48 to $2,400. The product line includes LA Series silicon oxide arrestors, MO Series MOV arrestors, CA Series capacitors, and TLC complete protection packages, serving voltage ranges from 0-100V DC to 0-2300V AC.

Product overview

Delta Lightning Arrestors manufactures a comprehensive portfolio of silicon oxide varistor (SOV) surge protection devices designed to protect electrical equipment from lightning and voltage surges. The product line is organized into three main categories: LA Series silicon oxide arrestors (including LA60x, LA30x, high voltage LA80x/LA150x/LA2301, and DC models LA602DC/LA302DC), MO Series MOV-based surge arrestors (MO302/MO303/MO603), and CA Series surge capacitors (CA603/CA302R). Additional products include cathodic protectors (LA101/LA104/LA105), phone line protectors (TA304), and complete lightning control systems (TLC250/TLC650). The LA Series forms the core silicon technology platform, while MO Series provides MOV alternatives and CA Series capacitors supplement arrestors by handling low-energy surges too fast for arrestors to respond. High voltage models (800-2300V) serve oilfield and industrial applications, DC models serve photovoltaic systems, and complete TLC packages combine MOV, SOV and capacitor protection for comprehensive coverage. Accessories include mounting brackets, lead options, and display units.
