Its design focuses on providing a durable and safe electrical connection path in outdoor or semi-protected environments.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe cable features a single conductive core made from tinned copper wire. The tinning process helps protect the copper from oxidation and corrosion over time, which is beneficial for long-term outdoor use. Both the primary insulation and the outer sheath are constructed from low-smoke, halogen-free material. This type of insulation is designed to limit the emission of dense smoke and toxic halogen gases in the event of a fire, contributing to a safer installation environment. The insulation thickness conforms to relevant industry standards for its voltage class.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe cable is offered with a nominal cross-section ranging from 2.5 mm to 6 mm, which correlates to its current-carrying capacity. The maximum outer diameter of the wire falls within the same 2.5-6 mm range. It is available in five pre-cut lengths: 1 metre, 2 metres, 3 metres, 5 metres, and 10 metres. These set lengths allow for straightforward planning without the need for cutting and terminating on-site for shorter runs, though they limit customisation between these intervals. The choice of black or red sheathing provides a simple method for identifying positive and negative lines within a solar array.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and red single core MC4 solar panel extension cable on a reel with tinned copper conductor.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/600\/2025-10-02\/original-image\/1617949532840.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis cable is designated for photovoltaic systems, functioning as an extension cable to bridge gaps between components. Its specifications make it suited for defined professional and project-based applications.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eIn professional solar installations, this cable is used to interconnect solar panels within an array or to extend the reach from a panel string to a combiner box or inverter. Its rating for medium and low voltage power cables up to 35 kV covers typical residential and many commercial solar system voltages. The availability of different lengths helps installers minimise waste and select the most appropriate cable for each specific run, aiding in a tidy and efficient system layout. The halogen-free insulation may be specified for installations where enhanced fire safety is a priority, such as in public buildings or areas with specific electrical codes.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor DIY solar projects or home renewable energy setups, this cable provides a ready-to-use component for expanding an existing system or building a new small-scale array. The pre-terminated lengths eliminate the need for specialist crimping tools for the cable itself, simplifying the process. The colour options allow for basic system organisation, helping to ensure correct polarity connections, which is crucial for system efficiency and safety. It is a practical component for connecting off-grid solar panels to charge controllers or battery banks.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and red single core MC4 solar panel extension cable on a reel with tinned copper conductor.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/600\/2025-10-02\/original-image\/1617949545008.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe value of this solar extension cable lies in its specified construction and the practical convenience of its available options. It addresses common needs in photovoltaic system building with a focus on material safety and installation flexibility.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThe tinned copper core is intended to offer better resistance to environmental factors compared to bare copper, which can support longer service life with less degradation in connectivity. The halogen-free insulation is a material choice that adds a layer of safety for the lifespan of the installation, as it does not rely on halogen compounds that can release corrosive acids when burned. As a component within a larger system, its maintenance is generally passive, requiring only periodic visual checks for damage as part of overall system upkeep.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis cable offers a straightforward solution for solar panel interconnection where a specific, set length is required. The combination of a tinned conductor and halogen-free insulation provides a balanced focus on both electrical performance and fire safety, which are key considerations in permanent energy installations. The range of lengths from 1 to 10 metres covers many common spacing scenarios in solar arrays, and the two colour choices aid in simple system wiring. It is a component designed to fulfil a specific role in a photovoltaic system based on its stated materials and specifications.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and red single core MC4 solar panel extension cable on a reel with tinned copper conductor.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/600\/2025-10-02\/original-image\/1617949545019.webp\"\u003e\u003c\/div\u003e","brand":"test333kb194i56sm","offers":[{"title":"Red \/ 1M","offer_id":54299889303891,"sku":"CJSM107233406FU","price":36.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 10M","offer_id":54299889336659,"sku":"CJSM107233410JQ","price":44.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 5M","offer_id":54299889369427,"sku":"CJSM107233404DW","price":41.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 2M","offer_id":54299889402195,"sku":"CJSM107233402BY","price":38.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 1M","offer_id":54299889434963,"sku":"CJSM107233401AZ","price":36.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 5M","offer_id":54299889467731,"sku":"CJSM107233409IR","price":41.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 3M","offer_id":54299889500499,"sku":"CJSM107233403CX","price":39.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 2M","offer_id":54299889533267,"sku":"CJSM107233407GT","price":38.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 3M","offer_id":54299889566035,"sku":"CJSM107233408HS","price":39.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 10M","offer_id":54299889598803,"sku":"CJSM107233405EV","price":44.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/5040\/0083\/files\/1617949532820.webp?v=1783977164","url":"https:\/\/0bdwuw-t1.myshopify.com\/products\/mc4-solar-panel-cable-single-core-photovoltaic-extension-cable-with-tinned-copper-wire-and-low-smoke-halogen-free-insulation-available-in-black-or-red-for-2-5mm-to-6mm-cross-section-lengths-from-1-metre-to-10-metres","provider":"TerraCraft.uk","version":"1.0","type":"link"}
